So, what are the best leveling blocks for a class C?
There are some interlocks for the Big Foot to prevent operation. One is the engine running. I think the other is transmission in Park, not Neutral (or any other gear).
Also, there is a fused 30 amp power supply that does not come from the controller. The controller just supplies the control signals to each of the hydraulic pumps.
I would would first check the interlocks. It's easy to overlook using the Big Foot with the engine running. I've done it a couple times myself.
