I have 4.10 gearing Not sure how that affects things with the overdrive.

It is possible for me to do most of my driving at close to 35 mph or lower but I have to determine is it better to do lots of stop signs/lights or is it better to use the highway and do 55 with a lot fewer stops. With my old truck the highway was better so long as I made certain to keep it between 50 and 55 mph. 65 was enough out of the optimal rpm that I lost close to 30% the truck couldn't do 75 but I'm sure it wouldn't have been better.

Yes I definitely use it as a truck. 75% of it's miles since I got it have had a load in the bed. usually it's full of firewood so far but todays load is grass and dirt heading one way mulch coming back.

Thanks for all the suggestions so far. I'll keep an eye out for a vacuum gauge next time I'm near somewhere that will carry one.
