By all means, call Jerry and let him pour some of his experience into you. Brace yourself. This is "drinking from a fire hose!"
I don't know what you've camped in, but if this is your first time driving a "big box" be aware of clearances. Not just height but also house body width, rear overhang, turning radius and rear overhang side swing on tight turns.
With a DIESEL engine in your Super C, you get one outstanding benefit. You can use the Truck Lanes at fuel stops! This allows a much easier in-fuel-out than even "RV Lanes" at places like Flying J, let alone the ordinary car islands, even if they have diesel fuel. Best I can tell, few to zero Truck Lanes still sell Gasoline, so I have to pick my fueling spots. You should have less worries.
