I've used Curt products before and this one did not disappoint. The packaging however was not up to the task. The box was open and I immediately started inspecting for damages and missing parts, thankfully the packer from etrailer completely wrapped the loose parts in reinforced tape and everything was there.

All set up, ready to roll. etrailer got me everything I needed hitch to brake control. Thank you your customer service was great!



by:

The hitch that we ordered was shipped the day of our order and came very quickly. The installation process was simple and worked very well on our bus. This gives us the capability to tow a small trailer to carry our luggage for the youth conferences that our teens attend throughout the year.



by:

Got it, looks like everything is there, the box didn't hold up to well to the ups shipping, typical, a smaller box packed with foam and bubble wrap may work better



by:

Well built product. Easy install, took about 1 hour mostly for drilling holes. Be sure you have at least 2 brill bits for each size required.

Received quickly and was just what I needed to solve my storage needs. Looking forward to putting it on my 5th wheel in the coming weeks.

Worked great for the application needed.



by:

Very pleased with this hitch, it fits my Thomas HDX bus with very little modification. only had to drill two additional holes in the frame. extreamly rugged and up for the job.



by:

Ordered this to retro fit a Class III hitch on a '63 Willys truck. So far it works perfectly. Was able to attach it directly to the frame and not lose any functionality. Also ordered C45791 Hitch extender and won't need it with this setup. All parts were included and the install instructions were clean. eTrailer also did a great job of assisting with the order to ensure that it got to me as quickly was possible.



by:

I actually ordered the wrong hitch; however, gave to a friend that needed one. He likes it. I ordered the same hitch but the 71 or 72 inch span. Had to customize the mounting to the fifth wheel camper as the camper had electric stabilizers installed. Anyway, works well, tow an 18ft deep V boat behind camper.

Good hitch easy install just drill some holes and bolt it on.



by:

Bought this to put on the back of my fifth wheel for bikes and the product is well made and instructions were good.



by:

Had it welded to the back of my pull trailer to hold a wire rack. Holds my camping chairs and dog enclosures, works great



by:

Hitch worked out great. Mounted it on the back of my 5th wheel. Use it to tow a Kubota RTV or my dog trailer.

I received the hitch on time and installed it with no problems at all.

Thanks!

  • Trailer Hitch for 2017 Keystone Carbon 357
    You will need to measure the distance between the side stanchions on your 2017 Keystone Carbon 357 to determine fit. The Curt Adjustable Trailer Hitch Receiver, # C13701 is for frames that are 18" to 51" in width. This is designed to work on box frames, C channel frames, or I beam frames and will fit most frames. This is a Class III hitch with a 2" receiver and has a lifetime warranty which speaks to its durability.

  • Can I Drill Holes in the Brackets of the Trailer Hitch Receiver to Match RV Frame Holes?
    I definitely see the logic in drilling holes in the mounting bracket of the Curt Adjustable Trailer Hitch Receiver - 18"-51" Wide - 2" Drop - Class III - 2" # C13701 versus the frame of your RV, however it isn't that easy. If you were to move the bracket attachment holes, then you would minimize the weight capacity and stability of the trailer hitch receiver as well as void the warranty on the hitch. The installation would be easier for sure, but I can't recommend going this route as...

  • How to Determine if a Camper Trailer Can Tow a Small Boat Trailer
    Most likely you would be fine since it looks like you have a solid square bumper that is welded to your trailer frame, but you really would need to contact the trailer manufacturer to determine if your trailer is rated for towing and what it's towing capacities would be. You also will need to check the local DOT in your area to make sure you can tow two trailers.

  • Recommended Trailer Hitch for a 2018 Sundance Travel Trailer
    The Curt Adjustable Trailer Hitch Receiver # C13701 is a great choice for adding a trailer hitch on your 2018 Sundance travel trailer. This is compatible with frame widths from 18" - 51" wide so you just need to confirm how wide your frame is to determine if this will fit. A review video and installation instructions have been linked for you to reference as well.

The overall height of the side bracket is 5-1/2 inches. The picture you mentioned didn't make it through, but I hope those were the dimensions you were looking for.

  • Recommended Trailer Hitch Receiver for 2002 Newmar Mountain Aire Motorhome
    For your 2002 Newmar Mountain Aire Motorhome, the Curt Adjustable Trailer Hitch Receiver - 18"-51" Wide - 2" Drop - Class III - 2" # C13701 will be the closest option to the capacity you are seeking. It is rated for 5,000 lbs without a weight distribution system or 6,000 lbs utilizing one. There is not an RV rated hitch receiver compatible with the 10,000 lb capacity you are seeking, so you may need to look to a custom welder to assist you in making one if that is a requirement.

  • Trailer Hitch to Carry Mobility Scooter on the Back of a 2014 Keystone Cougar
    Curt trailer hitch # C13701 is one option. It will fit frame widths from 18 inches to 51 inches. Frame width is measured from the outside of one frame rail to the outside of the other. This hitch is rated for 500 pounds tongue weight so it can handle the combined 400 pounds of the scooter and carrier. I recommend first checking the underside of your Keystone Cougar to determine if this hitch will fit or if any modification will need to be done in order for this or any hitch to fit. If...

  • Recommended 5th Wheel Trailer Hitch Receiver for Flat Towing a Vehicle
    The best option we have for your 2008 Keystone Montana 3585sa is the Curt Adjustable Trailer Hitch Receiver - 18"-51" Wide - 2" Drop - Class III - 2" # C13701. This has a towing capacity of 5,000 lbs, so as long as your car has a GVWR less than 5,000 lbs you can use it in this manner. If you'd like recommendations to get your flat towing system for your car, let me know the year, make and model and I'd be happy to assist.

So, it sounds like you would be restricted by the total towing capacity of the hitch. The strongest RV hitch we have is the Curt Adjustable Trailer Hitch Receiver - 18"-51" Wide - 2" Drop - Class III - 2" # C13701 which has a max towing capacity of 5,000 lbs or 6,000 lbs when using weight distribution.
