First long trip... got problems. Not happy.

Guys,

Thanks for the suggestions. After modding about every vehicle I've ever owned, I know all too well the effects of adding another mod without fixing the current problem. And as anal as I am, there is no way I won't make it perfect first.

I took the truck to my shop and put it on the lift. On the bright side, I found why I have a vibration problem. I can grab the rear of the front driveshaft and wiggle it back and forth at least 1/8". The bushings/bearings in the front of the transfer case is worn out. I'm not sure that came from an out of balance driveshaft or the fact that the truck has 53K miles on it and with the new driveshaft, it became more apparent.

I guess you're right Phil, 10mpg isn't bad considering my average speed was 69 mph over 1200 miles. That's a pretty high average speed. Other than when we got stuck in traffic, we were running 80'ish the whole time. I guess averaging 10 isn't bad.

Besides, I didn't buy the H2 for gas mileage.

Hey Phil, you said you LOWERED the shift points?? I did the opposite. I raised them to drag out whatever particular gear I was in and therefore raising rpms before it shifted.

Should I have lowered it and made it shift sooner?

Thanks everyone for the help.
