BTW, how would you plan to store it? Do you have a garage to store it in, or would you park it outside (learn to winterize it), or in a storage yard? We roll our pup into the unfinished portion of our basement which is open to the garage so keeping it indoors means you don't have to winterize it, the roof caulk wont dry and crack as soon, and it won't fade and get dirty sitting outside.
And WHATEVER you do, always, ALWAYS put some DAMPRID in it when you close it up. Damprid absorbs moisture on the inside which can create a moldy smell and stain the inside of your canvas. Moisture from rain, moisture from condensed breathing while you sleep, A/C condensate, any kind. Using Damprid from Day #1 was the 2nd best piece of advice we got.
