For anybody in a dealership, or I suppose a mechanic, or also I suppose anybody who knows more than me (everybody); does leaving a vehicle on those really steep display ramps have any negative consequences for any of the fluid filled bits? Like say an engine or transmission? I have no reason to ask other than 100% curiosity. Every time I see one it gets me wondering. Does it not matter at all? The trucks / Jeeps I’ve seen like this tend not to move all too often.
