Hi, I just bought a van since the family is getting larger. Both of my dogs are in crates in the back and I am wondering if I can fabricate a step connected to the rear hitch so that I do not need to deal with a ramp. I am thinking about A small platform made out of metal or wood that is attached or bolted to the hitch and can come off and on easily so that I am not driving with the hitch connected. There are pet steps that I see on Amazon however they are in the $250 range, I'm thinking a hitch with some DIY skills should keep me much cheaper. Any suggestions on the design? I was wondering if there is some sort of clamp that I can attach to the platform and the hitch so that the platform can be removed easily without messing with the hitch itself. Thank you
