I have one, haven't paid it any attention for a long time. You'll find that your suzuki will lean way farther then the inclinometer will read both sideways and forwards/backwards. I was thinking like you, in that I could pay attention to it and figure out my vehicles limitations. Waste of money in my opionion. You could purchase one at most autoparts stores, or any rv dealership as people put them on thier rv's to level them out.
