If things go bad you could always turn your van into a bumper pull trailer

I'd be inclined to pull the differential and remove the ring gear and then put it all back together. Less drag. And of course add the gear oil to lube the wheel bearings.

A load leveling hitch may be of benefit in such a build too.

With the engine and transmission removed,  a nice bit of space could be freed up for storage of light bulky stuff.

A person could run up on a class B with a high mileage engine/transmission for cheap.  When I was in teen years I drove a delivery truck at night. One of the guys I worked with got a job offer in Texas.  He had a good car so he went to a Junk Yard and bought a station wagon and found a tow bar. Had them pull the engine, transmission & seats for him.  Loaded everything he had in it like a trailer and off to Texas he went.  He kept the battery to run the parking lights after dark.  When he got to Texas and got all of his moving & set up done, he sold the rig to another junk yard there.

At one time I had thought about doing that using an 80's Toyota van or Dodge Caravan.

Backing up would be a problem.

Lots of people just bought an old school bus or truck and sold them upon arrival. It seems today to be the same with utility trailers.

If the home made version is to much for you, you can always go the 80 grand route.
