Jennifer --    You certainly should not buy this without inspection by a
qualified tech person.  If the seller will not agree the deal is contingent
on the results of an inspection, RUN -- do not walk -- to the nearest exit.
The seller should hold a nominal deposit and then refund this if your
mechanic is negative.

Don't be pressured by remarks that a 'hot buyer' is on the way.  This is
usually smoke.   Others on the List can comment on the price.  How many
Wisconsin winters has this camper seen?  I used to live in Chicago and know
the kind of pervasive damage you get from midwestern road salt.  It's not
obvious until you get under the vehicle, or pull some electrical connectors.
Quick test: horn should blow loudly.  Ask how owner 3 knew owner 1...

Possibly some List member in Wisconsin can help you.  Should be a few in the
Madison area, certainly.....??

Best of luck,
