Took the ol rig on fishing trip this long break, left in 3rd with the OD locked out - roughly 500 mile round trip with most highway miles thru the hill country of southern & eastern Wv with the tires & tall gears - 14-16 mpg.
EGT's werent a problem at all except when I tried to use OD a couple times as the temps would climb quick due to the low lugging of the engine.
Tires did great in a big rainstorm on the way back & almost no roadnoise that can be heard over the purr of the PSD.
Now for my rant & this really gets my goat -mad
I ordered up these tires & wheels fully expecting that they would have the proper center caps to fit a pre super duty truck since our bolt pattern was so easy to get - after getting over a dozen caps from 4 wheel parts there isnt a one in the pile that will work on the front or rear. This was after sitting on the phone with Weld's customer service guy Brett & then contacting Prestige who makes/imports their caps which they pretty much refused to help by acting surprised that Weld would send me to them for a cap to fit the truck
That really chaps my
