Even though this is a tent question, I'm posting here instead of the light gear section for reasons that will become clear. A friend of mine has asked my help picking out a tent, and I know he's not going to want to spend much money on it at all, so light weight is out the door (the same reason I made mine of plastic). I know he could use a tarp and still get by cheap and light, but I think it would be cruel on my part to leave him exposed to the mosquitoes. He'll be wanting something that sleeps at least two and maybe as many as four. Are there certain things he should look for in a department store type tent, or is it pretty much one's as good as the other at this level?
