We park HappyJack2 in the back yard uncovered and I beleive the original owners did also since it was new. I considered a cover but reading about problems on the forums it seemed more trouble than it was worth i.e. lasts only a few years, falling of rig trying to install etc. I priced out a metal carport at about $1000 and may go that route instead. Re-caulking seams seems to be good idea and was recommended to be done on a regular basis in some thing I read. I noticed some caulked seams starting to raise when I changed the vent cover that blew off last fall but didn't get it done before winter set in. With it parked in the back yard I check it out after rain /snow and weekly and so far no problems. I wonder how much CW would charge to re-caulk?
