Thanks again for all the input. I have come to the conclusion, from all of the experence here, that althougt a metal or fiberglass roof would be prefered a rubber roof in good condition can be repaired, reconditioned and made to last a long time. The products that were mentioned would solve a lot of problems, as long as the original roof was not totally neglected or abused. I believe I will not let the rubber roof scare me away from a potential unit, just do a real good inspection of it. As has always been the case, when I ask a question here, the responce is awsome.
There is an excellent article about replacing a rubber roof in this months (june'09) Motor Home magazine. After reading it you'll know wether you can do this or not. I wouldn't...
Last fall I had the Coachmen facility inspect my roof, and they sealed around the TV antenna. Other than that, it's good to go. The service guy said the roof should last as long as the coach, unless it's physically damaged (think low-hanging branches).
