As MadMedic said, some people have no clue about gears. Going from 3.73's to 4.30's means 14% more torque to the ground. That's a BIG difference.We've heard of a few catalytic converters getting clogged in the '99-2000 range, based on mileage and age. You might want to check that out.
Besides all that, there is something seriously wrong if you're getting such bad gas mileage.
Important: What size tires are you running?

I have 3.73s and 285s and the combination is fine up to about 10k lbs, when I tow both the boat and camper I'm 17k-18k lbs and I can hold 70mph up 6% grades, it does use 2nd at 4100rpm to do so but it does it without complaint! You have other problems, like someone else said, don't regear it untill you get everything else solved!

Sure sounds like a fuel filter. I know mine was night and day difference when I pulled the bad fuel filter off. More power, revs faster, and better fuel mileage. I know you mentioned that it has been replaced but for under $10 (don`t forget the special tools bout $8) you can have peace of mind that it is new and working good. Just my .02

on the flats the truck will rev up fine and pick up like h$#@ but under any load a hill or towing that is were the power loss is or it will shift down on the smallest of knolls which it did not seem to do untill the reflsh was performed may be i am reaching for a answer but that is what it seems like i maybe wrong
