Review of Curt RV Hitch C13702

Today we're going to be taking a look at the Curt adjustable width trailer hitch for RVs. This universal hitch is designed for use on RVs and motor homes. It's going to come with everything that you see laid out here on the table. It's also going to come with some detailed installation instructions to help walk you through that whole process step by step. The unique design of this hitch that makes it a universal design is really these slide along frame brackets. These heavy duty side brackets are going to allow for maximum adjustability.

They slide over the ins of the hitch and then you can slide these to wherever you need for your application. This particular hitch is designed to fit frame widths from 18 inches to 51 inches wide. It's going to work on box frames, C-channel frame, or I-beam frame. It's going to let you position the two mounts inward or toward the front or the rear. That's going to allow you to put the hitch body in the best location for clearance for your particular application. Now installation hardware is all laid out here on the table that is included for bolt on installation.

If you are doing a bolt on installation, drilling is required. You'll need to drill into the tubing of the hitch to get these attached to it. Once you have your location set, then you'll need to drill into the frame of your RV or motor home to get these brackets attached to it as well. The unit can be welded on as well. If you choose to do that, but again the hardware for a bolt on installation is included. Now the hitch itself is going to feature a high gloss black powder coated finish, it's going to do a great job at resisting rust and corrosion.

It's going to be resistant to scratches and UV damage. It's going to feature secure all-frame attachment. It's a nice steel construction for maximum strength and safety. Your receiver opening is a two inch by two inch opening. The pin holes on this unit will accept a standard 5/8 inch diameter pin or hitch lock.

You're going to have your nice large safety chain connection points. One on each side of your two inch by two inch receiver tube. It's going to feature a class three rating. The maximum gross trailer weight capacity is 5,000 pounds or 6,000 pounds if used with weight distribution. Tongue weight maximum is 500 pounds or 600 pounds if used with weight distribution. On these brackets that attach to the framing of RV and motor home, the distance between these mount holes that's going to be eight and 5/8 of an inch. From the center of the hitch pin hole to the receiver opening is two and a half inches. From the cross tube to the opening is six and a quarter. From the back of the cross tube to the receiver opening is eight and 3/4 of an inch. Curt also puts a limited lifetime warranty on this unit. Now please keep in mind that this is for use with RV approved accessories only. The main hitch body tube can be trimmed so that the ends are flush with the frame brackets, 51 inches end to end all the way down to 18 inches. If you have your frame brackets located right here, you're going to have a lot of excess. That can be trimmed off for a nice clean installation overall finish. Now if you do that, you will want to coat the bare metal with paint to protect against rust and corrosion. If welding this hitch, all welding surfaces must be cleaned to bare metal or the weld will not be the required strength and may void the warranty. That's going to do it for today's look at the adjustable width trailer hitch for RVs.

This is a universal trailer hitch with adjustable mount brackets. Since it will fit 18" to 51" wide frames it will fit just fine for your application.
