I'm glad I'm not the only one that thinks about things like this while I am out mowing lol I had thought about doing that exact same thing, a major downfall with having a drive thru door on the side of the enclosed is space. 1. I loose alot of wall space to hang equipment, blowers, trimmers, etc. also trying to jockey around my walk behind and Walker might be a problem. 2. I have some lawns that are on very small lots. So trying to find a good spot to park and drop the side gate on the enclosed would be a problem, as opposed to keeping it in the rear where it is.
