Amerigo campers were built in the northwest, somewhere in Washington I believe. I'm not sure when they began, but the last ones were probably built around the late 70s. The company was around for about another 15 years, and also made travel trailers, but I don't think they continued making campers. They are very unique with the side entry and expandable bed on the back, and the fact they're made of fiberglass. And they are LARGE.
Living in the northwest, I see them show up for sale now and then. Unless it is in REALLY good shape, I certainly wouldn't pay anywhere near $2000. The last few I have seen for sale topped out at around $1200, and were on the market for at least a couple of months. One was down to $600 the last time I talked to the seller. Another one recently started out at $500, and then over a period of a couple of months dropped to $200, then $100.
Amerigo campers are probably like Studebakers and Ramblers. Nobody wants them, and they aren't worth much until them become collectible. Which may or may not be in my lifetime.
I've never seen one without a refrigerator. If you find one without, someone probably removed it. And a 40 year old camper with the refrigerator removed is just about worthless because of the expense of replacing it. A working refrigerator is usually the most valuable item in an old camper.
If you're in the northwest they're not rare, just not real common. Elsewhere around the country they're probably pretty scarce. So if you really want one you may pay a premium for it. It all depends on how badly you want it.
