"Oh, c'mon now, I'm being serious. "
Me too Dargo. I have found several that couldn't do it. I carry my 600 lb-ft wrench (named Excalibur) with me and let them use it. The Alcoa aluminum rims are adapted to my Dodge with CNC billet adapter plates since at the time I did the upgrade there were no rims to fit the pattern available. Therefore the standard Dodge lugs are not what you use to change a tire. I bought through a TDR advertiser back in '97.
I also have found several brake shops, a tranny shop, and various others that can't lift my truck. It is fitted with a Stahl Grand Challenger service body and an aftermarket 65 gal tank. It is NOT light, especially when it has the largest Lance brand cab over camper on it.
I carry Excalibur at all times, just in case.
P.S. the 450 lb-ft should have been a clue as that is not Dodge specs.
