I was going to follow the inquiry thread on portable garages, but I thought I would "get Lost"
sorry... Anyway...
I bought a 26'-0 x 36'-0 x 12'-0 portable garage from sheltersofamerica.com
A real serious garage... heavy-guage tarp, heavy duty galvanized poles, delivered to my driveway in 4 days, in 2 huge boxes... erection was fairly easy, need at least 2 strong people... I bought mine when I saw one that has been standing against northeast winters for about 9 years in Connecticut, with almost no wear... Guy who owns this one says he only pulled the snow off after significant snowfall of appro. 15"... Snow pulls real easy due to slope of garage, otherwise it shows zero effects thus far... That was good enough for me, so I bought one...
Be forwarned if you buy one like mine, the boxes total about 1600 lbs, so help is needed to get off the truck... otherwise smaller sizes should be easier to handle and erect... Good luck!
