We have the hemi 282RK and love it. The Hemi is the top of the salem line, but it doesn't compare, fit and finish wise, to say a Cedar Creek. The hardware is not residential cabinet quality, etc., but we are satisfied with ours. No real problems. I think it is good $$$ value and you won't be dissatisfied.
If you intend to full time it, know that the Hemi, or for that matter most all FR products are not 4 season units. They claim to have heated underbellies however that means the furnace duct runs through the same space as the water lines. The Hemispheres do not have heated tank pads, valves, or as good insulation as other units. They are very good 3 season units, but not 4.
If you're looking at 4 season units, I would suggest Redwoods, Cardinals, Rushmores, Alpine, or Grand Design to name a few which would be better 4 season units. However $$$ goes up exponentially.
