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.

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

  • Difference Between Curt Adjustable Trailer Hitches 13703 and 13704
  • The difference between the Curt Adjustable Width Trailer Hitch Receivers # 13703 and # C13704 are a couple things, starting with the # C13704 having a 5,000 lb towing capacity and 500 lb tongue weight capacity while the # 13703 has a a 3,500 lb towing capacity and 350 lb tongue weight capacity. Both fit box frames, C-channel frames, or I-beam frames, though the # C13704 is for frames 22" to 68-1/2" wide while the # 13703 is for 22" to 72" wide frames. The Stabilizing Straps # 18050...

  • 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...

  • 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...

  • Is It Possible to Install Trailer Hitch on 2006 K-Z Escalade Trailer
  • It is absolutely possible to install a trailer hitch on your 2006 K-Z Escalade trailer; it will only require that your trailer have a box frame, C-channel frame, or I-beam frame that is between 22 inches and 72 inches wide. Should your trailer have that you will be able to use the Adjustable Width Trailer Hitch Receiver for RVs # 13703 which will can either bolt or weld onto your trailer's frame.

  • 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...

  • Best Solution for Carrying E-Bike on a Travel Trailer Using a Carrier with a Ramp
  • I do have a couple of solutions for you but you do have a very unique situation so there isn't a perfect solution that is able to address all of your concerns. The best solution is to install a trailer hitch like the Adjustable Width Trailer Hitch Receiver # C13704 (which fits frames from 22" to 68-1/2" wide) on your travel trailer and then use the Ultra-Fab Dirt Bike Carrier # UF48-979033 to carry your bike. Since this has a ramp (like the EasyFold XT #TH903202) it will help make loading...

  • Recommended Trailer Hitch for a 2019 Forest River Rockwood Ultra Lite with Welded Bumper
  • Thanks for the photo! I can now see the issues you are having trying to install a trailer hitch on your 2019 Forest River Rockwood Ultra Lite Fifth Wheel. That said, the brackets for the Adjustable Width Trailer Hitch Receiver part # 13703 and the Adjustable Width Trailer Hitch Receiver part # C13704 are too large to attach to the square tubing used to attach your bumper and this square tubing would get in the way if you tired to mount the hitch to the frame underneath.

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...

For a bolt-on option, I recommend the Curt Adjustable Width Trailer Hitch Receiver for RVs, 22" to 72" Wide # C13704 which is rated for trailers up to 3,500 lbs and 350 lb tongue weight. You can alternatively use the Curt # 13703 which uses a different style bracket...

  • Recommended Trailer Hitch for 2019 Coachman Freedom Express Ultra Lite 248RBS
  • 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...

There was a generation change between 1994-1995 which means it is not a direct fit for you. They did not offer a front mount trailer hitch for the second generation (1995-2003) therefore your best option would be to use the Adjustable Width Trailer Hitch Receiver part # C13704 and modify it to make it work for you.

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...
