Great looking unit! We had a 1996 Dodge based Roadtrek 190P and it may have been the best all around rv we have ever owned. They had one of two engines, ours was the smaller 318 (5.2L I think it was). Both are great motors and we found the smaller one plenty good for everywhere. It would slow quite a bit on Rocky Mountain passes, but hay, so what? I mention this because the PW and RT are very similar from those years and both high quality.
Please consider buying new tires before you leave Austin. Six year old tires are starting their natural rubber changes even though the treads are fine. Your PC weighs a bunch and you really will be safer on new E rated tires. You can search these forums for a lot of discussion on tires for Bs and we all have our favorites. If you are going to buy them in Seattle anyway, why not just do it before you leave and be safe in that long drive up there. Just a suggestion. Changing tires on these pups is no fun, particularly out in the middle of no where.
