I have been hauling around a couple of work boxes lately, maybe 500lbs total extra weight, truck sure does ride better. In addition to that, I hooked up my box trailer today, 16' twin axle, loaded to about 5,000lb and down the road I went. 60mph in 5th gear and the truck rode like a Lincoln town car, was more quiet than usual, almost as if it was meant to have that kind of weight all the time. I come to a 4 lane high way and make a right turn. straighten out in second and put the go pedal to the floor. 2200 rpm's she comes on strong and pulls to 3700 ish, hit third and watch the gauges. Boost to 9.5 psi, pyro pushes to 1000deg for the first time since the rally I would guess. come up to 60mph in third and hit 4th for another 10mph. Here we go, cruising like a champ. Hit a red light and do it all over again.This time I see the temp coming up on 210* and hear the fan clutch lock up and start cooling things off. Go pedal to the floor through 1st, second and third see 3700rpm's again, hit 4th for a bit and right into OD. This time the temp has receded to less than 200 deg and all is well. Get to my destination and let the truck idle for about 10 minutes after I back the trailer in place It was nice giving the ol' girl a workout even though it wasn't an extreme amount of weight to pull. Fueled her up and double checked my recovery gear also. Ready for Hurricane Sandy now.
