My apologies if this has been covered but I'm trying to figure out a wood shed. I was considering building my own but my busy schedule is getting in the way and lumber is spendy. I'm wondering if anyone has used a heavy duty type car canopy/tent? If so, how did it hold up? I've been searching and found some similar to the below. I know there are some cheap ones but I've sound some that appear to be more heavy duty. Ideally I would like all four sides to roll up and then roll a couple down during the winter. These could be more cost effective than building a lumber shed if they can hold up.
