Question:

Hi, I am interested in the Stromberg Carlson hitch part SC45MR to see if it will work on my fifth wheel. I plan on bolting it to the flange on the I beam frame using the included angle brackets. There is a 10 inch C channel bumper bolted to the frame. The angle brackets will but up against the C channel bumper. Can you tell me how far the hitch tube would extend past the end of the angle brackets so I know how far it will extend past the bumper. I would like to use a U bolt around the hitch tube just behind the flange on the end to bolt up to the flange on the C channel bumper for extra support. Is there room for the U bolt between the end flange and the hole for the hitch pin? Thanks

Hey Dusty, thanks for reaching out. I went out to our warehouse and grabbed one of the Stromberg Carlson Adjustable Accessory Hitch Receivers # SC45MR to grab the measurements you asked for.

The end of the hitch tube will extend out past the angle brackets by approximately 2".

As far as fitting a U-bolt between the safety chain loops and hitch pin hole, I don't think that's happening. The safety chain flange extends just past the edge of the pin hole, so there would be no way to fit a U-bolt between those. I snapped a picture from the side showing how close they are. If you want to add a U-bolt, you'd have to modify the safety chain loops, that or put one rearward of the hitch pin hole.

What were you planning on using the hitch for?
