Just got back from the maiden voyage. 2 weeks, 2500 miles. Camper performed flawlessly. Only "real" issue was the door to the garage would not stay closed while moving. I stuck a cardboard box between the door and strap for the cycle to keep it closed during transit.
As for the comment on the double pane windows, I don't think it was necessary, especially at the $2000+ cost plus the added weight. Maybe if we were full-timing. Most nights it was high 20s and one night it got into the high teens. Camper stayed warm with the fire place and furnace set to 70. The floor was really the only cold part of the whole camper.
The ram 2500 performed better than expected. The airbags seemed to really help from what I can tell. I ran 35lbs and it was the sweet spot. I carried about 100 gallons of freshwater the whole trip to offset the weight of the cycle in the rear. The only thing I will change with the setup is to get more aggressive gearing on the truck. The factory 3.42s are OK for the flat lands, but it's lacking a little on grades over 5%. I think some 3.73/4.11s will work the turbo less resulting in better MPGs too. I would like to lower the front a notch on the hitch, but I am afraid it would be too close to the bed. I am current sitting about 6" which is what everyone says it should be... It seemed to tow ok so maybe it's fine.
I will do a full report when I get a chance. Here's a couple pictures in the mean time.
