"Once you get it started it will come up pretty easily." Didn't find this to be too true, but I did get it off. I have found that I have scraped off the old, cleaned with mineral spirits and applied the new Daycron 10 (? spelling) Self Leveling sealant. This seems to work. Any better solution?

It does work but won't know how well until it warms up a bit. I read somewhere that one owner felt the basement air was marginal in hot climates. I guess that's why someone added a roof unit to help the basement air on this coach. The basement air conditioner is also a heat pump! If you wish, PM me and I'll send you links to removing, repairing, and re-installing your Coleman unit. It is basically built like a household unit with 2 compressors inside instead of 1, to make it a 24,000btu unit. Any Air conditioner repairman can service it once you have the links to the instructions for removal and re-installation. Some are saying the Coleman unit is no longer available -not true.

rsbilledwards Report post Posted December 26, 2018 Herman, the term is relative to age...I am ten years younger than you are, so easier. It is a job of patience and will. I can get the sealant up from around a 14 X 14 in about thirty minutes and about 90 percent in one shot. I used a big blunt screwdriver to work the outer edge all around. Then I cut through at a corner and all the way around at the outer edge of the flange and work with the tool till it begins to come up. It came off the flange plastic easier than the roof. Once I can get a hold of it then I pull straight up and work the sealant at the release point pulling only enough to keep a strain on the material as it comes up. Once you get it to this point it comes up pretty steadily, do not pull so hard as to allow it to pull apart and mostly in one piece. I know if you were standing there it would be completely different. Where the sealant releases on it's own it will be shiny white clean. The remainder is just pickin at and a little acetone. Acetone leaves no residue of an kind and the surface ready to reseal. Mineral spirits leaves a film so wipe with acetone after use. Share this post Link to post Share on other sites

Thanks for responding to all of us, looking forward to seeing a great looking coach from you in the future. May the coming year be the best for all! Hi Kaypsmith, I have a few photos of my friends Renegade that I helped him re skin almost 2 years ago. As you can see the aluminum was badly oxidized with many holes. I don't think I will need to do all of my Alfa but will take a closer look and make a decision. In any event that will not be a priority as the other issues are more important. Happy New Year!!

He is the ultimate authority IMO for these basement units. He's helped many owners with their units, and has a long list of where and how to obtain replacement and upgraded parts. The only thing different, as I said, is this unit has 2 120VAC compressors inside, where standard household units have 1 large 240VAC compressor. I have several links to parts from Bill's website,and even new OEM units are available, if you need my links. Duner's information should be all you need though.

Repairing the leaks up top. The simplest way to assure no more leaks assuming the vent covers are sound... Pull all the existing sealant up from the base and reinstall. Once you get it started it will come up pretty easily. Two school of thoughts on this include using Eternabond tape and overlaying the seamed area, body of the vent onto the roof. I like the Dicor self-leveling sealant. It is available online for as little as 8 bucks a tube thru Amazon buying multiple tubes at once. At the same time I would pull all the screws which most likely will have been zinc plated and now rusty from ambient moisture and replace with stainless steel ones. It may be necessary to go one size larger as the wool/Luan may be compromised. Reseal liberally with the Dicore. Allow a minimum of a month before painting as it takes that long for the stuff to dry sufficiently, just ask how I know. Sealing the cap to roof is best done with the Eternabond tape. This tape thru RV supply houses is very expensive. Buying it thru the roofing industry or the construction industry it is very reasonable . However there are Johnny come lately tapes that claim the same performance, not! Buy the Eternabond branded tape, white one side and sticky the other side. The fan vents and height, Yes you can use the sit up in the air and add additional height with the suggested MAXXAIR covers about 12 inches tall. A better solution are the premium fan assemblies MAXXAIR and Fantastic make that are even better with dark colored lids and that when folded down closed are only 5 inches tall. The are automatic, variable speed, push air out and or pull air in and are very quiet. They retrofit to the standard 14 X 14 inch hole. One of the best sources for parts is PPL Motorhomes.com parts superstore. When on sale everything is cheaper than all the other places particularly big ticket items and post is very reasonable. Shop for what you need at Camping World so you know what not to pay and buy online it will save you a wheelbarrow full of money.

kaypsmith Report post Posted December 29, 2018 I sometimes wonder if salt wont corrode fiberglass! Well maybe not fiberglass but my brother owned homes right on the beach near PC Florida, and the salt air down there did a number on almost every kind of metal except high grade stainless, aluminum was one of the worst to sustain damage from the salt.
