Well i finally did it - i got the big ladder out and climbed on top of the trailer ---- i was very concerned about doing so --- well i don't think i needed to be --- it was concerning me being on the roof and not the condition of the roof itself.
with ease i was able to walk along, remove clean and replace the maxair vent covers plus check and recaulk some of what i determined to be areas of concern.
glad that is over and that i no longer fear the roof!
