I pull an ’05 13 footer. It has the RM2123 Dometic fridge. The Dometic manual states, “level the vehicle when stopping for more than an hour.” So, my question is, how level is level?”

When I park for a bit to stretch my legs and grab a sandwich, should I be breaking out the Stanley carpenter level and my assortment of 2x8 lumber pads? Is the fridge going to go up in smoke for the lack of one piece of lumber under a wheel? Does the Stanley's bubble have to be dead nuts centered, or will the Dometic tolerate a ¼ bubble off, or even a ½ bubble?

At a campground I understand seeking the perfect centered bubble, but if I were to stop along a creek for a couple of hours of fishing? I'd be interested in your opinions.
