My understanding and experience with DICOR self leveling sealant cure times is that it takes about a month or so for the DICOR to cure enough that it won't adhere to anything that is pushed into it (think cover pulled tight over a corner with the sealant around that area being "crushed" by the cover)

Hypothetically, apply sealant in late October/early November, cover the trailer a week or so later, then it rains, turning to snow and pushes the cover down even more into the DICOR. The temperature increases, snow melts, but cover remains adhered to the sealant (that has not yet cured).... Repeat through the entire winter, and then "literally pull the cover off the RV" in the spring....

Will it happen? Maybe/maybe not, but if you clean and maintain your roof, reseal the roof then cover it, the sealant likely won't be cured. If you wait till spring to seal the roof, should there be a void in the sealant from towing the trailer (movement pulls the roof structure making voids more likely while towing), if (BIG LETTERS) there is a leak AND (more big letters) the cover happens to leak or rip or be blown off, then the "holes in the roof that weren't sealed" are an "open invitation to allow water into the RV"......

So, to summarize: If you seal the roof just before covering the trailer, the sealant may stick to the cover. If you wait until spring, if there's a leak and the cover fails, you increase the risk of water damage.
