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. 222031

  • RV Hitch and Cargo Carrier Recommendations to Allow Transporting 190-lb Generator
  • We offer two varieties of trailer hitch receivers for use on RVs, the bolt-on 4-1/2 x 4-inch-bumper-mount type such as the Ultra-Fab 2-Inch Motor Home Trailer Hitch Receiver # UF35-946401 that you referenced, and the higher-capacity multi-fit frame-mount type like the Curt # C13701. I suggest you check your RV owner's manual for any guidance or restrictions regarding the use of bumper- or frame-mount hitches and accessories.

  • Parts Needed to Flat Tow a 2012 Chevrolet Equinox with a Blue Ox Alpha Tow Bar
  • To tow your 2012 Chevy Equinox your first priority would be to have a trailer hitch mounted to your RV that is capable of towing your vehicle. My research shows that the Equinox weighs approximately 4000 lbs, not including fluids and cargo, and that it is flat towable as is. You should also refer to your owners manual to confirm the flat towing procedures for you 2012 Chevy Equinox.

  • Trailer Hitch Recommendation for a 2003 Coachmen Mirada on a Ford Chassis
  • We may have a trailer hitch that will work with your 2003 Coachmen Mirada, however the Curt Custom Fit Class V Trailer Hitch, # C14048, that you referenced will not fit Class A motor homes. Before installing a Class V trailer hitch on your Mirada, I recommend checking your owners manual or with an RV dealer to determine the towing capacity of your motor home. Most motor homes do not have high towing capacities, so a Class V hitch may be overkill. Our Class V trailer hitches are universal...

All of these have a square cross tube, 2-inch receiver opening and are rated for either 3500-lbs or 5000-lbs gross trailer weight. In your application I recommend one of the higher-capacity hitches. You'll want to check your trailer's frame width for a proper fit. Hitch # UF35-946403 from Ultra-Fab is a bolt-on type that fits frame...

  • Curt Stabilizing Strap for Adjustable Width RV Hitch # 13703
  • Per the warranty of the Curt # 13703, a stabilizing strap like part # 18050 would need to be used for hitch accessories like bike racks or cargo carriers. The strap is designed to provide additional support for the hitch mounted accessory. Curt has the same warranty stipulation on their Class I and II passenger vehicle hitches (as well as some of the Class III's). Finding a place to attach the hook on the end of the strap is usually pretty simple, but can be more difficult with a motorhome. Other...

  • When using Curt Class I and II 1-1/4-inch trailer hitches and some Class III hitches, such as the Curt Adjustable Width RV Trailer Hitch # 13703 you referenced, you will need to use a stabilizer strap like the Curt Stabilizer Strap # 18050 on items such as bike racks, cargo carriers, etc., or else the warranty Curt provides will be voided. The Curt hitch features a 3500-lb GTW and a 350-lb tongue weight with side brackets that fit frames from 22- to 72-inches wide. The purpose of the...

  • Trailer Hitch Receiver Recommendation for 1970 Chevrolet Chevelle
  • Although we do not have a custom fit hitch available for your 1970 Chevrolet Chevelle, I have a hitch that should work for you. Take a look at the Curt Adjustable Trailer Hitch Receiver, # C13701. This is a universal style hitch receiver that will fit frame widths of 18 inches to 51 inches and can be bolted or welded to the frame. Since the frame of a Chevelle is not 51 inches wide, you will need to make sure that you have enough clearance past the frame for the longer cross tube or...

  • Trailer Hitch Recommendations for a 16 Foot Airstream Bambi Sport Travel Trailer
  • I am not sure what the problem is at the front of the frame of your Airstream trailer. Especially since at the front the generators would be supported in more than one spot. At the back the frame would have to support the hitch and a carrier with the generators in the carrier. Now at the front it does increase the tongue weight of the trailer and that would make it possibly too heavy for the trailer hitch on the tow vehicle or for the tow vehicle itself. For a hitch I recommend something...

  • Recommended Frame-Mount RV Trailer Hitch for 2016 Palomino Puma 253FBS
  • The Curt hitch you referenced, Adjustable Trailer Hitch Receiver # C13701, fits trailer frames up to 51-inches wide (measured outside to outside) and so it will not work on your Palomino Puma that has a frame width of 68-1/2-inches. A better fit is Curt's RV hitch # 13703 which fits frames up to 72-inches wide. An install video is linked for reference. You can use the linked photo of the hitch mounting bracket that shows it's dimensions to see if there is enough clearance to mount it. This...

  • Trailer Hitch Fits for 2016 Forest River Crusader 28RL 5th Wheel Trailer
  • All of the hitches we offer for use on the rear of a motor home, 5th wheel or other RV are the 2-inch size. A Class II hitch has a 1-1/4-inch receiver opening. No hitches of this size are offered for use on trailers due to the high mechanical stresses that can be found at the rear of an RV. I checked the specs for your 2016 Forest River 28RL but I could not confirm the frame dimensions or rear bumper construction. If you have a continuously-welded 4-inch steel bumper you can use Ultra-Fab...

  • Hitch Recommendation for a Rockwood Roo Trailer
  • If your Rockwood Roo has a frame width between 31 and 46 inches you would want the Hidden Hitch part # 82200. This hitch has a 500 lb tongue weight capacity and a 5,000 lb total trailer weight capacity. Another hitch to consider is the Curt Hitch part # C13701 that will fit 18 to 51 inch frame widths and has a 500 lb tongue weight capacity and 6,000 lb total trailer weight capacity.

  • 500 lb Tongue Weight Capacity Hitch Recommendation for a Trailer
  • I believe I have a better solution, the Curt Hitch part # C13701 has a 500 lb capacity that will fit trailers that have frame members that are between 18 and 51 inches apart. Whether or not you could replace your current bumper with one rated for 500 lbs would be up to the manufacturer of your trailer, but I doubt they have a bumper available with that kind of rating so the hitch I recommended would be a better choice.

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 Front and Rear Trailer Hitch for Motorhome on 2004 Ford E450 Van Cutaway Chassis

For the rear hitch, if the outside to outside frame member width is between 18 to 51 inches, use the Curt Hitch # C13701. For a frame member width of 47 to 77 inches, use part # UF35-946403. Either hitch has plenty of capacity for carrying a bike rack and two bikes. Due to the fact that a Class C motorhome will have a long overhang at the rear...

  • Trailer Hitch Options for a 2008 Fleetwood Avalon Pop-Up Camper

I know many trailer manufacturers do not recommend towing a trailer behind another trailer for safety reasons and some pop-up campers are not even rated for towing. We...

When they tested it on a tube bumper, it was found to have a 3500 towing 350 lb tongue weight capacity. Since it hasn't been tested for the use you are proposing, the weight capacity would be completely unknown, which is why Curt doesn't recommend it.

This is a universal-fit service body truck hitch that can be installed by welding or by bolting-on with user-supplied grade 5 or better 5/8-inch diameter bolts and locking nuts. In any case welding is required to secure the cross tube to the brackets, even if the brackets are bolted on to the vehicle frame. The...

Curt hitches # C13702 and # C13701 are adjustable and will fit RV frames from 18 inches to 51 inches wide. You'll need to measure to make sure they will fit your RV's frame. The major difference between them is the # C13701 has a 2 inch drop. Both can either be welded or bolted to the frame.
