That was my gut feeling all along. With SD's many hills and valleys we
hit 5000 rpm's a few times. But with me being such a worry-wart I
figure i'ld bounce it off the masses before I make an ass out of myself
trying to explain it to the dealer (who doesn't know how big of a nutbag
i am yet). :)
I'm going on a trip tomorrow to pick up some stuff for ebay, so
hopefully the numbers will go back where they should be so i can put
this non-issue to bed! :)
