I can say this. When I go to the do it yourselfer car washes there is never enough room for anyone else to pull in behind me. Saying that I take up more than half the space. But on the downside there is only a few that I can fit in to. (26ft bus) As for my truck I do that in the drive way. exept for winter months. even than I have the plow on and I intentionaly take up a lot of room.
