we put our cover on yesterday, went smoothly, onlly took about an hour. we use the adco also, not tyvek though. we dont have the gutter extensions so we didnt have the problem of brekage. this will be our second year using the cover, didnt have any problem last year. we did seal up our external openings in water heater, refrig, and furnace grilles and placed some ant and mice traps inside. some people had tole me they seemed to have more trouble with mice with a cover, but i dont really understand why, maybe conincidence.
we use the cover on ou 23 ft hybrid.
