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.

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.

Our hitch has worked great! We pull our Jeep Wrangler behind or class A gas motorhome without any issues.

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.




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.

    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.

  • Towing Capacity for 1983 Skyline Class C Motorhome With C30 Engine
    Your photos didn't come through, but I think I can help with some information you provided. Your 1983 Skyline Motorhome does not have a specified towing rating that I can find. 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.

This hitch will be an excellent option for you so long as your frame rails are spaced between 18"-51" apart which they should. It has a class III rating with a 2" receiver tube opening. It also comes with all of the hardware needed for installation. I have attached a review video for you as well.

  • 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.

    The job boxes on your 2005 Ram 2500 will either need to be removed or if your trailer is tall enough for a level ride above them a 5th wheel hitch with a higher height setting could be used. I've linked the page to all your options to assist.

  • 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.

    I do have options for you but none of which I would recommend as an exact fit because the aftermarket trailer hitch manufacturers we carry (Draw-Tite/Curt) do not make hitches that are designed to fit specific RV chassis's. The only options I can offer you are universal like the Curt Adjustable Trailer Hitch Receiver part # C13701. This hitch fits frames spaced between 18" and 52" apart. It has a 5,000 max gross trailer trailer weight (GTW) and 500 max tongue weight (TW) rating. It comes...

    A frame-mounted hitch for your Keystone Passport is a much better option than a bumper-mount type, both for stability and for weight capacity. We offer several frame-mount RV hitches with capacities up to 500-lbs of tongue weight. All such items are shown on the linked page. The key is checking your trailer's frame width to find the best match and the required capacity. We also have some with drop, such as Curt # C13701 which has its 2-inch receiver 2-inches below the crosstube.
