Hi Roy, and welcome to the group.
For the most part members hereabouts are molded fiberglass
trailer owners, and while much of the coach related questions can be fielded, chassis and driveline questions may go begging.
There are also Toyota Camper and Nissan Motorhome special interest groups in the yahoo groups area that you might want to join in for more specific issues as well as get-togethers.
On them I am known as Sunrader Bob, P.I.T.A (Provider of Inconvenient Toyhome Advice)
