I'm only asking because I finally got an inclinometer and installed it tonight. I went to my place of employment because we have a loading dock with a very steep angle on it. I pulled up on it with only one side to get my truck on an angle, and only got to about 27 or so degrees before I myself started feeling somewhat uncomfortable. The truck felt fine, but I didn't. The gauge goes to 45, not like I'd ever push it that far. I want to know how far I could push it before I'd have to worry about a roll over.
