This is a follow up to this thread and it is now several months later.
I moved the motorhome to Explorer Insurance who specialized only in RV, RV TOADS, and Tow Vehicles (trucks)and they not only have no surcharge for a non driving family household member but in fact gave me a substantial discount over the GMAC offer.
I am pleased.
I am sure sorry that GM is going bankrupt but I can begin to understand why. I also have two of their cars and have had similiar problems with their warranties on them.
Incidently my wife just retired from 40 years in the insurance business as a Comercial Lines Broker and account manager, so we/she do know a little bit about insurance and insurance companies and the state comissioners political office.
Thanks again to all who posted.
I did get this included in all the RV magazines that I am a member or subscriber too and I think that is most of them.
Best to all,
Bebop.
PS: I am 76 this year and would have no objection to both or either a written and driving test in your own RV. In fact I would encourage it based on some of the drivers I have seen, listened to or talked to
