Video Transcript for Review of Ultra-Fab Products RV and Camper Hitch - RV Bumper Mount Hitch - UF35-946402

Hello everybody, this is Jeff at etrailer.com. Today we're gonna take a look at this Ultra-Fab two inch Motor Home Trailer Hitch Receiver for four inch by four inch steel bumpers, has a 3,500 pound gross towing weight capacity. Now, this powder coated steel hitch receiver is designed to clamp around your RV's four inch square bumper, and it provides this two inch receiver opening for your hitch mounted accessories such as bike racks, cargo carriers, or you can even use it for light towing. Now, this hitch receiver can only be mounted onto a four inch square continuous steel welded bumper, it's not designed for aluminum bumpers. This is a heavy-duty steel construction, does have a maximum gross trailer weight capacity of 3,500 pounds. Now, one note on that is you do not wanna exceed the weight rating of the bumper it attaches to, and it has a maximum tongue weight of 100 pounds.

If you noticed, if I show you the bottom of it, you can see it does have the safety loops on each side for connecting your safety chains to. We mentioned the black powder coat finish on it, provides rust and corrosion resistance, and this is a nice bolt-on installation, it includes all the mounting hardware, you can see I've pretty much installed it onto the part just to show you where it all goes, and it comes with a nice set of instructions that'll describe how it all goes together. Now, also I wanted to show you, if you look closely, right here and right at the very bottom, there's two large bolts here, these thread into the hitch receiver, and the reason those are on there is once you put your accessory in there, you tighten those down on the bottom and on the side, and it'll help reduce movement between the hitch mount and the receiver tube. Again, the application, you can see the U-bolts here, they are designed to fit four inch by four inch continuous steel welded RV bumpers. Receiver opening right up here is two inches by two inches, and one note is this is designed for use with RV approved accessories only.

Let me show you all the sides. But that should do it for the review on the Ultra-Fab two inch Motor Home Trailer Hitch Receiver for four inch by four inch steel bumpers.

Installed this hitch on my fifth wheel to pull my side by side to the upper peninsula in Michigan, however I would recommend that you be sure your bumper is capable of the weight being towed. I personally removed my existing bumper and welded on a much heavier steel bumper. This hitch did exactly what was expected of it, thanks so much to Kirstin for her help at checkout

This product has preformed as it should, no issues and I can be confident that it will withstand its purpose, thanks again



by:

hooked up hitch both u bolts broke dropping both bicycles on freeway in Montana. Just a fact and no total rack and bikes were well un der the maximum load rateing,



by:

Product fit perfect. Easy to install. Very happy with the hitch, Only one problem, the anti-wobble bolt on the side would not fit because U-bolt is in the way. You can only get the bottom anti-wobble bolt in. (See 2 pictures) I solved that problem by cutting off the end of the U-bolt that was in the way. They just need to move that hole back a bit more. Now I have both bolts on and cargo carrier is solid.



by:

Works as advertised. Simple to attach. I use it on the back of my camper an put a generator, extra fuel and loaded cooler. Thanks for great product.



by:

This fit very well, only problem is the side anti wobble bolt won’t fit when the U bolts are installed. Note submitted picture.

Kenneth

6/5/2022

Just ground off a 12 inch or so, installed bolt before the U bolt. Works fine now.



by:

This bracket provided me the means to mount the receiver style spare tire b racket on my Class C RV. By mounting it upside down, it placed the weight squarely on the frame, leaving the u-bolts to merely hold it in place.



by:

The bolts on the top are not long enough. I had to buy longer bolts. The bolt on the side that secures the hitch to reduce the movement is too long. The u-bolt is in the way. I had to buy a shorter bolt. The bolt hole needs to be repositioned so the u-bolt will not interfere.



by:

The product arrived ahead of schedule. etrailer upgraded my shipping at no extra cost! It fit on my bumper with very little problem. It was tight because of my chrome covering, but I expected that. I did have to replace two of the nuts that would screw on, and I had wanted to place it above the bumper but the body of the trailer wouldn't let me. I haven't gotten a bike carrier yet, but I wholly expect it to work just fine. I would have given it an excellent but for the bolts I had to replace.



by:

Works great used on trailer bumber for portable refrigerator to carry on cargo unit. Had to beef up bumper with angle iron due to weight ...no bounce at all with hitch



by:

I needed a way to carry our mountain bikes when we go traveling with a our RV. The Ultra-Fab Hitch receiver fit perfectly on the 4x4 rear bumper allowing me to carry our bike rack. I feel I could even tow my golf cart trailer behind my RV with this hitch if needed. Very easy to install with a simple socket set and torque wrench.



by:

This bolt on hitch worked as advertised. Important to get the bolts sufficiently tight. I used this product to hold a cargo carrier on 2020 Colorado camping trip.



by:

the item looked and worked as advertised



by:

Cold the cargo rack on the rear of our travel trailer.I bought it so that I can lock my generator to it when we’re traveling.



by:

Very easy to install (my four year old helped me). We used it for our bike rack on the back of the trailer so it was installed on top of the bumper instead of underneath. This thing holds it very solid.



by:

Product looks and feels very solid and well made. Only took me 5 mins to install. Can't wait to see how it performs as we head out in the next few days. I will be carrying my generators and gas and kids bikes on it. Thank you again etrailer.com for an easy purchase with all of the info i could ask for on your website to help make the best selection for my needs.



by:

Will not slide properly over my 2” hitch, machined wrong, the holes for the hitched pin indent in on the hitch, will not work. This is my second try, I wish they would inspect there products before sending them out as I am stuck with no way to move.. will be asking for a full refund.very disappointed!!

This is for mounting on motorhome bumpers not to mount on hitch receiver bars.



by:

Well constructed, very easy to install, negates fabricating or adapting a hitch by taking advantage of existing 4" bumper.



by:

E trailer is a consistent place I shop for fast delivery, great communication and products as described.



by:

The top bolts were half inch to short. I had to go buy longer ones that cost $x.xx then only one of my hitch shanks will go far enough in to line up the holes for the pin.

This trailer hitch is designed to fit your RV bumper measuring at 4 inches by 4 inches. I have sent your information over to our customer service department for them to get in touch with you.



by:

Bought (2) of them to make to make a removable rack for a small inflatable boat to carry on the back of the trailer bumper. Appears plenty strong have to see how it lasts. Did notice that the chain loops interfere with the 5/8" bent hitch pin hair pin connection. I'll have to make one out of a bolt (they should have though of that).

Etrailer Expert

Victoria B.

10/24/2019

Rather than a bolt, I recommend using a straight hitch pin, such as the etrailer Trailer Hitch Lock # e98882. This hitch pin has a locking end cap to keep your hitch accessory secure. The lock core is accessed on the end of the cap, making it easier to access in a hitch with limited space like this one.



by:

Just right to tow my little aluminum boat behind the camper !



by:

I mounted 2 on my camper bumper. One for a bike rack and the other for a swing away grill. Super happy w the product and the results.

Dave P.

3/24/2021

A year later, I couldn’t imagine not having the bikes and the grill on the back of the RV. Great product



by:

So far it was very easy to put on the Trailer, I used it for a cargo carrier to place a 3000 Honda Generator on the carrier, work great, the next thing I'm going to try is to pull my 2 Waverunners, but I will check the weight first..

Rich A.

7/3/2014

It has worked great, but now I have changed my Trailer and do not need it anymore



by:

The Ultra fab 2" RV Hitch Receiver for 4"x4" Bumpers is a very well made piece of steel. It fits our Wildwood Trailer Bumper perfectly. It is built so sturdy we have no worries about using it to haul our bicycles. It is rated at 3.5k!

Etrailer Expert

Thanks for the review Ron, but please also keep in mind that an RV approved bike rack should be used, and please make sure the bumper is appropriately for your use.



by:

I didn't use these as recommended, but they are working great. Most people mount one of these on the back bumper of their RV and then attach some way to carry a storage box or a bike rack. I didn't like the way they flop around going down the road. All that movement isn't good. Instead I purchased 2 of them and mounted them inline with the frame rails, then welded together a rack to affix a standard pickup tool box and mounted it in the hitches. This supports it from both sides and is stronger since it is mounted inline with the frame rails. They are working great and prevent any movement in the box. It's a rock solid mount.

  • Availability of Bumper Hitch that Can Fit 4 inch Square Bumper for Carrying Generator
    Only the RV manufacturer will be able to tell you if the bumper is strong enough for the weight of a carrier and generator, but we have the Ultra Fab bumper hitch part # UF35-946402 which is designed for 4 inch square bumpers and has a 350 lb tongue weight rating. Assuming your bumper is rated for the weight this would fit and work well.

  • Torque Values for Install Hardware for Ultra Fab Hitch UF35-946402
    When installing the Ultra Fab part # UF35-946402 you need to make a first pass of torquing all of the bolts to 30 ft lbs and then a final pass of 60 ft lbs.

  • Can the Ultra-Fab Motorhome Hitch Be Used to Haul a 280 Pound Lightweight Motorcycle
    This trailer hitch has a 350 pound tongue weight rating, so you will want to make sure that the weight of your Moped, and the carrier are under this combined weight rating. For hauling your Moped you will want to make sure that you are using an RV approved carrier. Due to the extended length from the rear axle to the receiver, the forces exerted on the carrier and cargo will be exaggerated. That is why this hitch is intended to be used in conjunction with RV-approved accessories only....

    On the Ultra-Fab 2-Inch Motor Home Trailer Hitch Receiver # UF35-946402 the included u-bolts have a material diameter of 7/16-inch. This means that the gap in your photo needs to be at least that large for the u-bolts to fit through. The u-bolt posts' center-to-center spacing is 4-5/8-inches. On the hitch assembly the four holes are 1/2-inch diameter. Left-to-right they are spaced 4-3/8-inches apart on hole centers, and 4-5/8-inches apart front-to-back.

  • Fitment and Compatibility of Bumper Mounted Receiver Hitch on a 2008 Jayco Camper
    Good news, the Ultra Fab RV Hitch # UF35-946402 will work for your Jayco 4 inch x 4 inch bumper. This hitch will provide you with a 2 inch hitch receiver opening. It is important to note that since you already have a spare tire carrier on the bumper your total weight must not exceed the 350lbs of tongue weight capability of your bumper. I have linked the Ultra-Fab Receiver Hitch to this page for your convenience.

  • Can Ultra-Fab 2 inch Motor Home Trailer Hitch part # UF35-946402 Install on Aluminum Bumper
    The trim piece you mentioned that is on your aluminum bumper is a fairly common style of bumper that the # UF35-946402 will fit on just like in the picture you referenced. You will want to check with the manufacturer of your trailer to determine if the bumper is rated for having a hitch like this installed on it. I attached a review video for this hitch for you to check out as well.

  • Could Two of Ultra-Fab 2" Motor Home Trailer Hitch Receivers # UF35-946402 Carry Motorcycle Carrier
    Two of the Ultra-Fab 2" Motor Home Trailer Hitch Receivers # UF35-946402 would in theory hold 650 lbs, but I believe there would be a weight capacity issue on the bumper of your Safari. I can't imagine it's rated for holding 650 lbs so you'd want to first confirm with them that you'd have the needed bumper capacity.

  • Could Ultra Fab Hitch Part # UF35-946402 Fit Bumper Measuring 3 inch by 3 inch
    Since your bumper is 3 inch by 3 inch the Ultra Fab hitch part # UF35-946402 that you referenced can fit it but you would need to use a 1 inch spacer on the top/bottom and another one on either side so that it fits properly since this is designed for a 4 inch by 4 inch bumper. The spacer would essentially make the bumper 4 inch by 4 inch.

    As long as the 4 inch square bumper on your 2017 Starcraft Satellite 17RB travel trailer is made of steel and welded its entire length then you would need hitch # UF35-946402 because it is the model for 4x4 inch bumpers. I have linked a video of this hitch for you. The combined weight of your carrier and the tote tank isn't very much but you will still want to check the trailer literature to make sure that the bumper is rated for carrying weight and. if so, the amount of weight it can handle.

  • Can an Enclosed Trailer be Towed Behind a 5th Wheel Trailer
    Towing one trailer behind another trailer is illegal in many places so the first thing you are going to want to do is check the laws where you will be traveling. It is also just not a good idea because it is not safe. The likelihood of jackknifing and a bad sway condition is greatly increased plus there is a lot more momentum pushing you forward. If installing a trailer hitch on the 5th wheel I strongly recommend a frame mounted hitch, not a bumper mount hitch. The bumper mount hitches...
