Not much activeity on the Prowlers forum but my wife and I really love our 29P Titanium addition. Now if when/if we go full time, wife is still working, we may upgrade to get a coach with better insulation, that could be a great benefit in extreme conditions and maybe one with a larger refrigerator as well. Other than those 2 items we are very pleased with the quality and features in the Prowler. For part time I don't think we would upgrade but we all know what 100 degree weather and lack of shade can do to the inside temps and don't think that I'd like to live that way all the time. I would hope the additional insulation of the luxury coaches would make a difference and be worth it in the long haul.
