Thanks for your input bionic man. My suburban can't pull 4th (overdrive) on level ground, level ground is 3rd gear, anything more than a slight incline for more than a half mile or so will cause it to shift to second. I wouldn't mind running some higher RPMs if running in the mountains or something, but in the Texas panhandle it seems a little much. I would consider an ecoboost, but have never seen one in my price range ( less than $10,000). I am sure they are out there, just not real common.
I like the full size van idea, but my wife has vetoed that option.
I think I will keep looking for a v10 or 8.1 chevy, sounds like they may do better than the 6.0 or my current 5.3.
My 5.3 will stay in overdrive on flat level highway pulling a 27 foot TT that weighs about 6500 wet. On the long uphills I pull it down to 3rd unless it's real steep then I go down to 2nd, roughly 45MPH. It is good to know that all the 5.3s do about the same. I have a buddy that has an 8th gen Suburban with the 5.7 and it seems to tow better than the 5.3.
My buddy has a Ford Expedition EL with the 5.4. It "seems" to pull better than the 5.3.
