I am considering the purchase of a 1982 Bluebird Wanderlodge and would like to find someone knowledgable to do a pre-purchase inspection. The RV is in the Milwaukee, WI area. It is a M35 model with a CAT diesel, non-turbocharged and 165k miles from new. It is mostly original but seems to be in very good condition. Any suggestions on a qualified inspector would be appreciated. Also, any comments on this year and model as a unit to own.
