It's free (and just takes a few minutes) to register with any of these auction companies. Lots of good stuff for sale, from used pickups, trailers, service bodies removed from trucks, deisel trucks and busses, etc.
maybe you should look at Park Model Homes. living room,full size kitchen, one bed room. Ck out Texas "Cavco's Family of Park Model Brands"
Because these are over 8' wide, they require a pro driver to move. With a tiny House or a travel trailer, you could move it with a rental truck AND move your storage stuff while you're at it. Just because of the size and the full-size appliances inside, chances are they are going to be a lot more than $20,000. I want to be a bit more mobile than that. Otherwise, they seem nice, though.

Instead of a park model, if you were going to have a trailer parked at one location for a long time, a "destination" trailer could work. They're sort of half way between a full-blown park model and a normal travel trailer. Not something you'd want to drag around constantly, but with more space than a typical travel trailer, with higher ceilings, residential-type applicances, etc. all in a 8.5' legal width with the slide-ins in.

Just buy an old skool bus and convert it how you please,tow a rig and use the bus as base camp.
Depending on your budget a good compromise may be an enclosed car hauler. I had a 20 footer, I paid 3k for it. Put in a kitchen counter, a refrigerator, lights and it was awesome. I towed it home with a Nissan Murano. If your careful and you dont have the trailer loaded down your scout may even be able to move it. You could source cheap used RV items from craigslist to finish it out too. You may even be able to find one already finished out.
These type of builds were very popular when I was in California
You might want to look at either the Little Guy T@b trailers or the discontinued T@da trailers of you don't need tons of room. They are going to be less expensive than a lot of trailers and I have read nothing but good stuff about their service. The newer T@b trailers have bathroom options and the T@das all had them. The T@das are roomier, if you can find a used one.
