Can Curt Multi Fit Hitch 13704 Install on Trailer with Boxed Frame 2025 NOBO 19.3

Updated 02/19/2026 | Published 02/11/2026

Question:

I have a 2025 NOBO 19.3 that I would like to add a hitch to. I believe the C13704 will work. My center to center of the box frame is 62.5. However I cannot find any install videos or instructions for the box frame. I assume this is a weld only application? Please advise, thanks.

Hey Joe, yes the Curt hitch part # C13704 can install on your 2025 NOBO 19.3 based on your frame width and style. Since you have a boxed frame you could weld the hitch on like you mentioned or you could use fish wire/bolt leaders to get hardware in place after drilling a hole in the frame. This actually comes with fishwire for this type of install as well. I attached a picture that covers how to fishwire as well. What are you wanting the hitch for?

Thanks! We plan to use it for a bike rack. 200lbs +/-

@Joe Nice! Do you have a bike rack already?

I mounted this box frame on my 2023 Sonic (made by Venture). I had to modify the stabilizer jack brackets but it works will. I bolted mine on. The sonic has c channel design. I previously had a bumper mount hitch for standard bikes but bought e bikes. The hitch works great. Keep in mind that you get more bounce on the rear of a trailer so be care in your selections of bike racks. Many do not recommend trailer mount in the fine print. My outfitter rack was recommended but derated the rack to 160 lbs down from 200 lbs. I am right at the limit. I added a cable around the hitch relievers just for added strength.

I installed this box hitch on my 2007 Wildcat 5th wheel camper, I believe 3 years ago now. It works perfectly for hauling my 18' Tracker Boat. It's very sturdy and easy to install. I used the bolt-on install and have had absolutely no issues. It was definitely cheaper and much safer than having it welded on. I would definitely purchase it again if ever needed.
