We bought (Nov. 2010) our TM from the original owner who kept it set up most of the time (near Denver, CO) in a yard with a lot of sun. He used it as a place to write and read out of the house. Our top bag seal cracked and sort of dry rotted through last summer, and I think this may be due to overexposure to the sun from this earlier nearly-constant exposure. So if you're going to leave it set up in the sun a lot, perhaps some kind of UV protectant or cover/shade on the bag seal would be a good idea. That is, if I'm not wrong about the cause of the seal cracking like that. Currently holding together with some good-quality gaffer's tape and still seals OK though.
