I feel like my truck might be geared lower. At 70 mph I'm pulling aboyut 2100-2200 rpms, but it feels like i should be at about 1800 for that speed.

Auto or 6sp, does it make a difference?

For me, I'm automatic.

its auto, stock tires, but i think when i go up to 33's it might help a little.

is it me or does it just feel like if there was an extra overdrive, the truck would just idle at 80.

but it sounds like I have the 3:73's as well

At 2K RPMs I'm doing about 74 now that I got rid of those 4:10s (auto). Cost me $1,700 to get them changed to 3:55s but it's a much quieter ride going down the highway and that makes it worth it to me.
