Lol me either, I thought it was older, regardless it's nice and clean, fully functional and ready to use, and I only payed $700 for it. Im happy. I have 4 other campers I'm buyer/seller/collector.
The serial number on my 87 lil bigfoot is 2B9LDFLA0H006102. I'm guessing they had the same counting digit series for all of the models but it would be interesting to know for sure.
