Welcome to the forum, and congratulations on your
Bigfoot purchase!
Seems like a pretty good price. Only way to judge is to research comps here and at
www.fiberglass-rv-4sale.com. Check current ads and recent
sold archives.
Comparing with new (current or original MSRP in 2002, not sure which you meant) is interesting but not useful. Only thing that matters is what folks are paying now. Some popular used models were selling for more than comparable new last year because the wait times for new builds was so long. Many older models are worth more than original MSRP, but inflation distorts the comparisons.
The market seems to be cooling a bit this year, not surprising given the price of gas, general inflation, a return to more normal work and school patterns, and falling values of investment portfolios.
