You'll have no problems using the Aluminum Liger Trailer Wheel - 15" x 5" Rim # LH34FR to replace your damaged 15" x 6" version. The tire will still fit just fine as they work on a range of different wheel widths, however since the wheel is 1" narrower overall that tire will sit 1/2"~ in from the others.
The wheel does not have a max PSI rating, that's dictated by the valve stem, and the included valve stem is rated to 65 PSI so you'll be just fine. view full answer...
Yes you can. If you have the # FOS05TASF already and just want to upgrade the monitor to a 7 inch version all you'd need is the # FR47FR. view full answer...
The Everchill RT 150 that you have now is very close to the Dometic RV AC units so the best chance we have for an easy replacement would be the Advent Air Unit part # ACDOM135 which was designed to replace Dometic units so the wiring would plug right in. view full answer...
