I was also looking at the Mountaineer 356tbf, but decided on the Gateway 3650BH. They are around the same price range, similar materials, similar insulation values, very similar layout…. but the tub in the 3650BH is what sold us. Also, I ordered mine from a wholesale dealer, added a washer/dryer, king bed, dinette with chairs, 6pt level system, dual pane windows, sofa in the back bunkhouse, residential fridge, and a 5 year extended warranty for less than the Mountaineer without those options. I am a little concerned on the TV placement, and would much rather if that second bench seat would be replaced with a fireplace and TV area instead. That would make more sense IMO, but that issue didn't outweigh the positives of this unit for us.
