$120? the RV tent is $2300 around here. its too tall it fit in anything smaller.
Same here. I agree. A small "Tempo" for sub-compact car, erectable plastic and metal framed car cover, with front (and rear) plastic doors costs $460++ around here.
Anyhow, you have to be really vigilant at cleaning the snow off those erectable outdoor storage tents, because in our region (just a few hours drive north of Mass), we have a lot of collapses during winter.
I hope you guys don't get the kind of snows this coming 2016 that you had last 2015 winter. We were watching the situation from the condo in Florida, last winter :E
On edit: just thinking out loud.....our marina wraps hundreds of boats this time of year. The only thing I would worry about is wrapping the roof properly. If there is a breach in the shrink- wrapping process on your roof area, you may develop a swimming pool up there, when the snow melts out... (not potentially deep water, but could be a serious problem none the less if you let your imagination wander a little at various scenarios)
