I would wash the roof like others have mentioned. Use a soft bristle brush, a car wash brush for example, and some non abrasive cleaner(roof cleaner). Do not use a pressure washer, nothing good can come of pressure washing a RV. Regular garden hose, water, soap, bucket and brush. There are coatings that you can buy to re seal the roof. I haven't used them myself. I would avoid using eternabond on the entire roof. I am up on my roof 2x a season, 1x at the beginning to check for any cracks in the caulking and once at the end to re-caulk and inspect. I have owned 4 trailers and have done this with every one. I am a big fan of dicor self levelling lap sealant. It's not extremely expensive and does the trick. If fact any monkey with a caulking gun can apply it. I have read that RV roofs are good for 12 years, however I have had an older unit that was meticulously maintained by the first owner and my roof was awesome never had an issue with it. Best of luck with everything.
Seems kind of foolish if you ask me. Slides have motors and tracks with teeth for lack of a better word. From what you describe it sounds like there may be a missing tooth or the gear in the slide motor is broken or slipping. Sounds like the dealer is taking you for a ride. If at all possible I would pick it up and take it somewhere else, if that's an option. I wouldn't pay them anything, they are the professionals. If this happens all the time then they should be pretty fast at diagnosing the issue and fixing it. Have you asked them for a break down or what they have done? Can you manually crank out the slide without any hiccups? Best of luck and Sorry about your situation.
I would say go for it. With aluminium siding I would just pull off any siding that is needed to access the bad wood. For all the naysayers, I would not listen to them. I rebuilt a camper a few years ago and I enjoyed every minute of it. Actually the wife and I keep playing with the idea of doing another. This is blog my wife started when we got our camper, everyone we talked to said that it could not be done. There is nothing like enjoying the fruits of your labor. In your endeavor you will realise how crappy these RV's are built from the factory and you will end up with a trailer that is better than new.
That was some excellent work!! I just read the blog, you did an amazing job on that trailer!
I've never seen a TT with a laundry chute! Or one that has a basement.
I had a Pilgrim 312bhss that had a "laundry chute", which was a carpeted cover/hinged lid on the topside of the pass through in the master bedroom. I would store a couple good sized laundry baskets under the lid and drop my laundry down into the pass through. It was awesome.
I have a sliding patio door on mine, its nice. Having the sliding door allows a lot of light to come in and also makes the interior feel more open. The only issue I have found is the dirt gets in the track.
