Hi I have the idea to mount my maxx traxx to the back of my Northstar pop up camper. I don't want to put holes in my camper walls so I'm trying to find a way to mount them to something attached to the 3 bolts on the camper Jack. So I guess a piece of metal to hold them to the leg bolts of the camper. Is there a camper Jack accessory mount anywhere? I can't find anything.
