Have spent the past month or so trying to decide on which RV to buy to fulltime with my wife. I have been looking at Excel, DRV, and did not focus on Landmark since in RV Consumer Group it was not listed as recommended for fulltiming. But after seeing the Monterey listed at a Camping World site that included a full-timers package - well obviously I checked out the Heartland site and now need a little more info since it has peaked my interest. My questions: (1) is the Landmark the "high-end" RV from Heartland and is Landmark the only brand recommended for full-timers? (2) I would like to visit Canada and Alaska eventually (Spring/Summer), how well does it handle the cold and of course the heat down here in Florida? (3) How is the service through Heartland if there are problems? Does Heartland assist if the dealer doesn't do their part? - The 2/5 warranty seems like they should. (4) at 16,500 GVWR I assume something in the line of a diesel F-350 dually would be enough power. I have never owned an RV before, but have been with family a few times in their RV, looking forward to joining the 1.3 million Americans full-timing. Thanks!
