Looking at purchasing a "portable garage" (aka, tent) for temp storage. Any recommendations?

Very little snow here at 115° in the summer (I've seen 123° on the back porch, in the shade). Heating the garage is not a problem.
The sun seems to kill them first.
And I've still got a fallen tree here to take care of too (16" trunk). Thankfully it didn't fall on the house, or our boundary fence.
