First of All, Thank You Daniel C. for starting this topic.
We are satisfied owners of a 2002 model 211-S with the 5.7 Chevy. Seem to be getting about 12-14 mpg depending on wind and speed. Have had adequate power. Have not had any problems with the coach in the first 4,000 miles. Had a leak around the dinette window fixed by the dealer before we took possession. Was raining on pickup day.
The posts have been educational and have provided a checklist for things to watch for. Several have asked about the raising of the couch front when the slide is pulled in. This is normally caused by overcranking because of how and where the jack screw is located. I have placed a rubber door stop under the rollers while traveling with the slide pulled in. This should minimize the load on the side walls of the slide if the rollers are carrying some weight.
I replaced the dinette table leg adjustment device with a bolt - this eliminated one minor rattle.
Road Trek's have a swivel passenger seat in the Chevy chassis. Should be able to order and fit to the B+ Trail Lite.
More later.
