In answer to your question about one year ago, I may be able to shed some
light on your Amerigo camper.
Amerigo started out as a truck camper company in 1970. They increased their line to 5th wheels, camper trailers, and park models until 1977 when they ceased production. The camper trailers made during that time were a
fiberglass shell. In 1991, they got back into the RV market by producing 5th wheels and camper trailers that had a standard aluminum siding skin but only lasted until the 1993 model year, then ceased production for good. During 1993, the widths of the camper trailers were 6' 8" wide as compared to 8' for previous models. So, if your trailer is 8' wide, it is from a previous year than 1993. If not, it is a 1993 model. Also, the 18' and 19' models had dual axles, whereas the 14, 16, and 16.5 foot models are single
axle. I hope this helps.
