I have a 2015 HW Flagstaff pup and the two major items that caused me to choose it was the electric roof lift system and then the bunk end supports. On my PUP i put the bunk supports in place before sliding the bunk drawers out onto them, this eliminates the back or shoulder lifts of other models and competitors. Then for the HW models your get counter height inside cabinets with no lifting galley into place, which also saves back, legs and arms for lifting the weight. Mine unit has the hard wall bath but the two sections rise from hinges on each side and are light weight to lift. The heaviest thing about my PUP is the portable dining table which I can still handle. My salesman was the worst and even said during the walk through that he hates PUPs, but I have always been a fan of PUPs and just worked around him.
Seems like a lot of setting up. To much work for me. Lol. I'd rather just back in a camp site plug in if need be and enjoy. Guess I'm just a little lazy. I am 65 so I can be after working most of my life away. Lol
