I do this with my frames periodically after building to take them to the powdercoater, unless there are more than one. It works pretty well, imo. Although I have never attempted to do it with the tubes in place, just the frame itself.
I have an EZ Packer. Custom made for the back of the motorhome so that we can also tow a car behind. When I get where I'm going, transfer the whole thing to the car. I've made several trips with this rig. The farthest being to Smithers, B.C. You will need to give him specifics, toon make & model, bumper/receiver dims, etc.
