Do you prefer a side-opening or end-opening tent? I’ve tried solo versions of both over the years, and come to prefer side opening. For one thing, I don’t have to sit-and-spin to get out of a side opening (nothing like a huge leg cramp as you fold yourself up to rotate when you need to answer nature’s call in the middle of the night.) For another, the vestibules seem larger (since they’re on the longer dimension of a solo tent) and it’s easier to stow gear out of the way.

I have noticed that end opening tents tend to weigh less.
