Video Transcript for Review of Curt RV and Camper Hitch - Frame Mount Hitch - C13704

Today we're going to take a look at the Curt Adjustable Width 2-inch Trailer Hitch Receiver for RVs. It has a 5000 pound weight capacity. Now this adjustable trailer receiver hitch, it's designed for use on RVs or motor homes, and it can be bolted to the vehicle frame or welded on for a no-drill application. They do use these heavy duty side frame brackets, which allow for maximum adjustability from 22 inches all the way out to 66 inch-wide frames. They'll just slide along the hitch body to match the width of the vehicle frame you're installing it on. And they will work on a box frame, a C-Channel frame, or even on I-beam frame.They do include everything shown here.

The grade A installation hardware to install it is all included. Nice set of detailed instructions. You can see all these parts here are of a nice high-gloss black powder coat finish. They do resist rust, corrosion, and they are resistant to scratches and UV damage.When you do install this, it does give you a strong, secure all-frame attachment. These frame brackets will bolt to the cross tube and to the vehicle frame.

It's a solid construction for maximum strength and safety. Now when you do install this, it is designed you could put a 2 inch ball mount in the receiver, to enable your RV to tow a variety of trailers, such as a boat trailer or ATV trailer, utility trailer. Or even a pop-up camper. A tow bar could also be attached, allowing you to bring your vehicle along for the ride.Now, it is not for use with a weight distribution system. Also, if you use this for non-trailer loads, like a bike rack, a cargo carrier, if you do install it on here, it must be supported by auxiliary stabilizing straps to secure it.

They do that have folds here that you can run the straps through, or you can even use those holes for the safety chains.It is for use with RV-approved accessories only. This part is made in the USA. Again, the receiver opening is 2 inch by 2 inch. It is a Class 3 rating, so the maximum gross trailer weight capacity is 5000 pounds. Maximum towing weight capacity is 500 pounds.A few measurements on this: it is designed, and it's adjustable to fit a frame width of a minimum of 22 inches, all the way to 66 inches.

Now the overall length of the whole tube itself from one end to the other is right at 68 1/2 inches. The overall length of the receiver tube from the back here of the cross tube to the very front, that measurement's going to be right at 11 inches. The distance from the front to the front of the. or the front of the crossbar to the receiver tube, that measurement is going to be right at 8 3/16 inches. Now the frame brackets, let me slide one of these off, give you some measurements on the bracket itself. The width on the bracket is right at 10 inches. The height is right at 5 1/2 inches tall. And the mounting holes on the top here center-to-center, they're going to measure right at 8 5/8 inches center-to-center.Now one note on this, the main hitch body, tube here, the cross tube, it can be trimmed. So in other words, if you find the correct frame width, this can be trimmed so that the ends are flush with the frame brackets. You could cut those off. But what you want to do is after trimming them, you do want to coat the bare metal with paint to protect it against rust and corrosion. And also, if you're going to weld this hitch, all welding surfaces must be cleaned to bare metal, or the weld's not going to give you the required strength and it may void the warranty.But that should do it for the review on the Curt Adjustable Width 2-inch Trailer Hitch Receiver for RVs, with a 5000 pound weight capacity.

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. 763670

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.

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. 578523

Ask the Experts about this Curt RV and Camper Hitch

  • Recommended Trailer Hitch Receiver For 5th Wheel Trailer Frame
    For your 69 inch frame measurement you can use the Curt Adjustable Width Trailer Hitch Receiver for RVs, 22" to 72" Wide # 13703 or # C13704 both of which have a tongue weight rating of 350 lbs but with different mounting styles. These both are bolt on options. There is also a weld on option in the Ultra-Fab 2" Trailer Hitch Receiver for Trailer Frames # UF35-946403. My recommendation is the Curt # C13704 based on the ease of installation with the bolt-on method from the bottom...

  • Where on Trailer Frame to Measure for Adjustable Width Trailer Hitch for RVs
    Thanks for all those measurements! There is a trailer hitch that will work great for your travel trailer, though the measurement you want to go with is from outside to outside, which you said was 70-1/2 inches. That means the correct hitch is the Adjustable Width Trailer Hitch Receiver for RVs, 22" to 72" Wide # 13703. This is a Class III hitch with a 2" receiver and 350 lb tongue weight capacity so you will be able to carry a good deal of cargo with it. For a cargo carrier on the rear...

  • Correct Adjustable Width Trailer Hitch for I-Beam Frame That is 69 Inches Wide
    The Adjustable Width Trailer Hitch Receiver for RVs, 22" to 68-1/2" Wide # C13704 is for frames that are a maximum of 68-1/2" wide so it is not the correct hitch for your 69" wide I-beam frame. For a frame of that width you would need the Adjustable Width Trailer Hitch Receiver for RVs, 22" to 72" Wide # 13703 though it has different brackets, and I've added a photo of their dimensions for you to take a look at. These brackets can be flipped (on both hitches) without issue. If that...

  • Bike Rack Recommendation for Carrying 60 lb Bike at Rear of Travel Trailer
    I do have a bike rack solution that will work well for your, but not every bike rack is designed for the rouger ride quality at the rear of a camper. I wish I could recommend the Thule EasyFold XT part # TH903202 for you as it is a great rack, but it shouldn't be used at the back of a travel trailer. The most similar option is the Swagman Escapee part # S64693 which has a 60 lb per bike capacity and can be used at the rear of a camper so it would work well for you. This would work great...
