I own a Dicks 2-man. Dicks carries 2 such stands, one has a full platform under the seat and the seat can fold up; the other just basically has an oversized foot rest, and there is no platform under the seat itself. I'd make sure I was getting the former kind.

I've been placing ladders on public land for 5+ years. I chain them up good. Lowes (& others, I'm sure) sell heavy-duty cables fairly cheap, and can be used to secure a stand pretty thoroughly.
