I wish we carried a programmer that would fit the Cummins engine you have in your motorhome but we don't since the wiring harnesses are different from the Dodge trucks.

I do have some tips that may help your motorhome perform at it's peak though.

Make sure both fuel filters are clean. There should be one on the frame and one on the engine.

Make sure the lift pump is in good working order, when they go out they tend to cause power loss.

Your crankshaft sensor could also need to be replaced.
