Another new Guy

[Philthytoo]

Hello, I may be in the wrong place here, but I recently came across an Amerigo truck camper that I couldn't pass up. It is in need of a total re-build. I wonder if some of you Amerigo trailer owners could give a clue to the part on the ID tag showing month and year. Mine has 1 and 1. So the January thing I think is a given, but what would the year be? 1971, 1981, 1991. I believe these were only made for a few years, and curiosity has set in.
I'm Phil, in California near China Lake. Also have a 1961 TravelEze trailer (project) and a '70's Alaskan camper (Major project).
