Question:

Will this fit a 34 inch outside distance frame? I am mounting on a 2003 GM built chassis.

Hey Mark, good to hear from you again!

In the past we've found that the wide bolt holes on the Curt Trailer Hitch Receiver # C15312 measure 39" center to center (see attached photo).

Since it sounds like your frame is a little different than the normal 2003 GM chassis, I still recommend sticking with the Draw-Tite # 41990-07 since it's in that universal-fit category.

What are your thoughts on the universal fit?

Thanks Jon. I need a bolt on with 5,000+ capacity, about a 6" drop and approx 31 1/2" bolt hole spacing in a similar design to 15312. There is some fabrication needed so I have some flexibilty on the bolt hole spacing. 41099 style could work in a bolt on version. Any suggestions?

@MarkA The 41099 has a 7" drop so it's honestly going to be the closest thing to what you're needing. It can be modified as-needed to fit your setup.

I spoke to my contacts at Curt and Reese and the only styles of hitches that can be made to fit a service body truck like your Fedex step van are multi-fit RV hitches like the #41990 that has a 16k capacity. This is a weld on hitch that would require…

I do have an option for you though there aren't custom fit hitches for box trucks. The frame is not really the issue but rather the body the up-fitter adds on which could hang down below the frame where the hitch mounts or actually use the holes…

Welding is not required for installation of the Multi-Fit Motorhome Trailer Hitch, item #5350. Once you have the tube cut to length, be sure it is centered on the vehicle, you will need to drill 1/2 inch holes in the cross tube to secure it to the…

Answer 6

Hi Pat, For a motorhome like yours, there is a hitch, and even a Class III like you were wanting, but it's a universal fit and not a custom fit. What you need that will fit your 39-1/2" frame spacing is a hitch from Draw-Tite: - Multi-Fit…

Hello Thorsten, thanks for reaching out. I do have an option for you, but unfortunately there are no custom fit hitches for the cutaway models of the 2002 Chevy express van. The only option is going to be a universal hitch like the Draw-Tite Ultra…

For your 2021 Mercedes-Benz Sprinter 2500 with the standard bumper, the Curt #C13388 and the Draw-Tite #75549. While we have not had a chance to install both of these hitches yet, when we measured these hitches we found that from the center of the…

Your best option is either going to be going with a Curt hitch, #15902, or going with one of the hitches with 16 inch brackets like #41990-16. This hitch is closest to what you need. You will need to have a qualified professional welder perform the…

Answer 12

I checked your order notes and it looks like your ordered the part #41990. You should note that this isn't intended as a front mount hitch and to install it you would normally want the part numbers #4907 for 7 inch brackets or part #4916 for 16…
