For those of you who have never heard an impact wrench.
This is NOT just a case of some people like this and some people hate that, and campers complaining for the sake of complaining about various noises in a CG.
Ever been in a tire shop and heard them putting tires on with an impact wrench? THAT is what we are talking about here. Only turn that thing on within a foot of your RV in the middle of the night while you are sound asleep.
IMHO there is NO gray area with using an impact wrench on RV levelers at a CG in the middle of the night. IMHO if you are that lazy to have to use one to lower or raise your levelers perhaps you ought not be camping.:(
