Is there an online version of the blue book (or something similar) for RVs and campers ?

www.kbb.com (kelly blue book)
and
www.nada.com

are both good blue books for cars and trucks,

but NADA goes a little further, and also has many other things: boats, planes, motorcycles, houses, classic cars, and YES, RV's

check the RV's out HERE
