Great Experience! I needed to find a hitch that could carry a bike rack on the back of a travel trailer. E-trailer very informative about finding the correct hitch. It arrived very quickly & the staff are great about following up on the progress of the order. The installation instructions were very clear to follow.



by:

Very well constructed, heavy duty hitch. I installed this on the back of my Arctic Fox 29-5T 5th wheel, in order to haul my generator on it. I had to add some 2" square steel stock as spacers to lower it enough to clear hard parts on the trailer. Only negative is the requirement for some odd sized, large drill bits.


Comments
High quality product that performs its task without any issues.
Marc M - 09/12/2021

I ordered a 66” adjustable hitch for the back of my Keystone fifth wheel. With fuel prices high, I want to pull another trailer for my side by side. It arrived in just two days. I had to weld it to my frame because of the way the back stabilizer jacks were but I think it will work great.



by:

The high quality, flexibility of a universal part, adaptability and ease of fabrication as well as installation made this product very user friendly. Also, a BIG thank you to Danielle in customer service (ext. 79394) who researched and looked until she found just what I was looking for from the shelf. Nice work ! As you look below at Warhawk, take note that this is the Hot Rod the hitch will be attached to...for the long haul.



by:

Installed the hitch in less than a day. I bolted it to the trailer frame. I have a rack on it for carrying a generator.


Comments
The hitch is strong and durable. It does not loosen when traveling and easily holds a generator.
Judd A - 10/28/2021

Curt's adjustable trailer hitch receiver worked as planned. I was looking for a hitch receiver that would be able to carry the 75 lb. weight of our double recumbent trike carrier. The camper bumper has a low weight rating and I wouldn't trust it to hold the carrier weight over the long term. I mounted the hitch assembly by both bolting it through the bottom of the camper frame and also welding side plates between the hitch assembly and camper frame. I also welded a plate between the receiver tongue and rear camper frame to minimize receiver flex. These additional plates should allow us to safely carry our two recumbent etrikes on the carrier if needed in an emergency. Total weight including carrier would be 175 – 200 lbs. Currently we carry the etrikes inside the camper on a custom rack.



by:

Just received this for my 18' Travel Trailer and the build on this item is really strong and heavy. I have not installed it yet but it is straight forward and looks quite simple.
I would definitely recommend this to my friends.
Also shipping was extremely fast and i have been using etrailer for better than 10 years now as they never let me down.
All heavy duty hardware is included which is not in the picture



by:

Heavy duty product - fasteners are well thought out. Highly recommend.



by:

I thought it interesting that it took almost a week to ship. It is installed and works great.



by:

Installed this on my 2019 Keystone Passport 2670BH for pulling a second trailer and it works perfectly. I did have to purchase a drawbar with a longer receiver so the trailer would clear the stock bumper on the camper. My campers bumper mounts wouldn't let me move the hitch further back and I didn't want to remove the stock bumper. Works great though. Very strong.



by:

As is typical of Curt products, this is extremely well built. Very clean painted finish. It might be a little challenging to drill the 5/8 holes for the mounting brackets as the the tubing is quite thick. I did it on a milling machine- a good drill press will work also. Otherwise, take your time and use a series of small drills to step up to the 5/8" I actually used a 21/32 as that is what it appears Curt puts in the mating part. This was overkill for my application. I put it on a Keystone Fuzion 371 Toy hauler. I have a pit bike and two beach cruisers. The mounting plate on the hauler is not designed for the full load of this hitch, but my intent is just for the bike rack.



by:

Fit perfectly and was as described. If you need to drill through your frame in order to mount it ... don't go cheap on the drill bits. Having a cheap oxide bit was my biggest frustration. I then purchased a quality bit and the job was super easy!



by:

Very helpful when talking to the customer service department... The hitch worked very well. Very satisfied with the hitch..



by:

Great quality. Follow directions and you will have no problem installing. I would recommend setting aside 2+ hours to put this hitch on if you do it solo.



by:

Always, easy to order always on time with no problems!



by:

Product was what was expected. I have not used it yet, but expect it to work well.
One issue with it is in the instructions. It lists tools needed to install. It states an 11/16” socket & wrench are required. I did not own that size, so I purchased some before fully investigating size of bolts. What is actually needed is 1” socket & wrench. Big difference. So completion of installation was delayed until I could get the needed tools.



by:

Excellent proactive customer service. I wish all my online purchase experiences were with etrailer.com as they have superior merchandise at reasonable prices and they follow that up with outstanding customer service. I'm elated how my hitch mounted on my camper.



by:

Hitch is fine. Only issue is those are some gigantic holes to drill by hand. 4x 11/16" Dia, and 4x 9/16" Dia in 1/4" steel. Sheww!!! Glad I did not break my wrist when the bit grabs as it breaks thru the farside about 20+ times. Using brand new high quality bits is must! If I were 50 I would definitely pay someone to install.



by:

this hitch fit perfect on the rear of my fifth wheel trailer and has pulled my swivel wheel trailer down the road with no problems.



by:

great product and services , unfourtunately I ordered wrong size, had to order another hitch



by:

This hitch is heavy duty and well made. Can't wait to get it installed.



by:

Well made and fits perfectly! Thanks etrailer for great products and service. I will purchase again when needed.



by:

Received order, product looked good all pieces and parts enclosed. Will install tomorrow. Will send photos and give installation critique. Thanks for following up, shows great customer service.



by:

The product was ordered and shipment was expedited promptly ,Order was received on the date indicated could not be more pleased !

  • How Far Does Curt Trailer Hitch C13704 Hang Down from the Vehicle Frame
    I went out to the warehouse and measured Curt trailer hitch # C13704 for you. The distance from the top of the mounting flanges to the top of the cross tube is 2 inches. I have included some pictures with additional measurements for you.

  • What Type of Frame Will Curt Adjustable Width Trailer Hitch # C13704 Fit
    The Curt Adjustable Width Trailer Hitch # C13704 is compatible with box frame, C-channel frame,and I-beam frame styles so as long as your frame is 22" to 68-1/2" wide this will fit on your RV. If you let me know what you plan on using the trailer hitch for I can make additional recommendations.

  • Can Brackets on Curt Adjustable Width Trailer Hitch Receiver Mount to Top of I-Beam
    The Curt Adjustable Width Trailer Hitch Receiver # C13704 that you referenced should be mounted to the bottom of the I-beam frame on your trailer. This is how the hitch was tested and rated by the manufacturer so altering the brackets so that they sit on top of the frame could result in an unknown, lesser weight capacity. I have attached the written installation instructions that you can check out as well.

  • Mounting Bracket Dimensions of Curt RV Hitch 13704
    The Adjustable Width Trailer Hitch Receiver for RVs, 22" to 66" Wide # C13704 has brackets that are 10 inches long with mounting holes 8-1/2 inches center on center. The height is right at 5-1/2 inches tall. I've attached a video to assist. The top of the receiver tube will sit about 2 inches from the bottom of your frame but the hitch ball height will be determined by your ball mount. I've attached an article to assist.

  • Weight Capacities of Curt Trailer Hitch # C13704
    The Curt Adjustable Width Trailer Hitch Receiver # C13704 referenced in your question features a 5,000 pound towing weight capacity and a 500 pound tongue weight limit. I verified this with Curt. This adjustable hitch is designed for use on trailer or RVs and will work on frame widths of 22 to 68-1/2 inches. I have attached a short video review that you can check out as well.

  • Fitment of Adjustable Width Trailer Hitch Receiver for RVs
    The Adjustable Width Trailer Hitch Receiver for RVs, 22" to 66" Wide, # C13704 has brackets that will mount to the bottom of the frame. The square tubing sets within these brackets which extend toward the inside of the frame. If you have a measurement of 68.5" from outside to outside, this will fit. See attached mounting instructions, image shows fitment.

  • Will the Adjustable Width Trailer Hitch Receiver for RVs Work on 5th Wheel for Boat Trailer
    The Adjustable Width Trailer Hitch Receiver for RVs part # C13704 will fit any frame with rails spaced between 22" - 66" apart. It works great on fifth wheel, gooseneck, and travel trailers. Simply clamp the hitch onto the bottom of the frame at the rear, drill the flange holes, trim the crosstube, and that's basically it. It can support up to 5,000 lbs so as long as the boat does not exceed this with trailer you'll be good to go.

    The cross-tube of the Adjustable Width Trailer Hitch Receiver, # C13704, slides inside a bracket that is mounted to the frame. These brackets cannot be mounted further than 66" on centerline from each other or there is too much of a gap for the cross-tube to set in. The brackets do not hold the cross-tube from the very ends of the tube, but the cross-tube sets inside of the brackets. If your frame is of steel tubing measure to the center of the steel tube on one side of frame to the...

    On the Ultra Lite trailers like your 2019 Coachman Freedom Express Ultra Lite 248RBS, the manufacturers don't reinforce the bumpers to be able to handle that weight so the torque on the bumper is too great. The best solution is to use the Curt Adjustable Width Trailer Hitch Receiver for RVs, 22" to 68-1/2" Wide # C13704 or up to 72 inch wide # 13703. This trailer hitch will mount to the frame of your trailer and will allow you to use a bike rack or cargo carrier on your trailer. If...

Since the frame is extended past the regular body length it could very well affect the towing capacity of your motorhome so it would be wise to do some research on that and maybe reach out to the manufacturer as well to get their take on it. If you don't have bolt holes readily available that would work with the 14053 hitch then you may consider using something...

  • Recommended Rear Hitch To Carry Bike Rack with COACHMEN RV APEX NANO 193BHS
    The best hitch will depend on the distance between the camper's frame members at the rear bumper area. If the camper is equipped with a bumper, you'll also need to be concerned with the drop that the hitch provides, which is the vertical distance between the underside of the frame member and the top of the hitch receiver tube. This ensures that the back bumper or fascia doesn't interfere with the hitch receiver tube. The Curt # C13704 you had looked at is pretty versatile. It's compatible...

    In the description of the Curt hitch part # C13704 we have the overall width of the hitch listed as 68-1/2 inches and the max frame width it can fit as 66 inches. Keep in mind that the frame width dimensions for the hitches we offer is measured from outside to outside of the frame rails so your measuring inside to inside 66-1/2 inch would not even be close to use with this unfortunately. So you'd be best off with the # 13703 although it does have the lower capacity.
