Sorry to hear about all the problems your having,
It must just be terrible
Our Fleetwood product is a 1982 Pace Arrow 30 ft. All original, Everything works, even the central vac, although I don't think they used it much it was clogged @ the tip with Carpet fibers and a cigarette butt (previous owners quite smoking back in 1973) I bet the builders used it last doing a Finale clean up
.
Getting her ready for our maiden voyage (New CD radio, with 7" pop up screen and a new CB radio, a dash cam, and a New 1080 smart TV) going to Tx and parts west, end of Dec. Our first year going to be snowbirds.
Maybe you should look at a vintage unit... Not so much to go wrong.
Tim.
