An interesting approach to avoid reprogramming the engine computer (and possibly voiding the warranty). If you have to take it to a dealer you'd simply remove it and they wouldn't be any wiser.
Personally I don't think I'd try it: Since I already have experience with a 5-Star tune on a previous vehicle I would be more inclined to put a 5-Star tune on my RV.

I would also prefer a tune however, my RAM is still under factory warranty and I don't want to take a risk with that. This add is 10 minutes on and off and not detectable. You're right also about changing fuel curve. Adds more fuel to curve. On my RAM, made a much, much faster off line starts and seems quicker passing response.
