You're best bet is to visit rvdirect.com and rvwholesalers.com and set it up with the options of the one you're looking at. The sign up and request a price quote (free). Then you have something to work with when it comes time to negotiate.
But you will be better prepared and have the information you need to make a good decision. If you have money growing on trees in your front yard, then the answer to your question is...Yes, 81k is a good price.
Good luck on your purchase, that's a beauty of a home.
