Actually the job is not as bad as you think......
We have re-done several Airstreams when things are slow at the shop. (Kind of a hobby for one of my business partners) Most of the couches and such are easily removed. Also easy to re-install afterwards. Just takes time and patience.
We have done an old single slide MH as well. I little tougher, but not too bad. If you are handy with a table saw or radial arm saw you will have very little problems.
The MH we did was a Monaco Dynasty (98) that had been in the rental fleet for some time and was looking kind of "Ratty" in the carpet dept. We did all of the MH in a wood laminate. (Except the bedroom, it got new carpet) Used 1\4 round to trim the edges with a transition piece between the carpet in the BR and the rest of the rig. Turned out better than we expected actually. Kind of surprised ourselves......
About a month after we finished it, someone came in and loved the flooring and the "Refresh" we had done on the interior and bought the rig......
When stuff slows down a bit, we got a 98 Dutchstar we want to go through........ But we ain't sellin that old girl when we are through.
Over 170,000 miles on her and she STILL drives and runs SWEET! (THe fact it is paid for helps too! )
