You aren't parking bigger than my 24' as shown in this space. This is not an unusual way ours gets used.

That was Memorial Day weekend at Penn State where my HS age daughter was playing in a volleyball tournament. It sure beat spending big bucks on jacked up hotel rates, if you were lucky enough to find a room even within an hour drive of State College.
I wouldn't want any smaller, but this size works great. 3 sleeping positions, 50 gallons total of water, and 30 gallons each of grey and black means two of us can live in it without hook-ups for 4-5 days.
