We're considering retiring and would like comments on what we should purchase for our "other" home, a RVA diesel pusher or a gas (assuming all other accessories are the same)? We would probably be in the rv for at least 6 months of the year. We have seen some early 90's pushers with only 50 - 75k miles on them and wonder about these. We don't really care about slides like the newer models but wouldn't through them out either. Comments?
