I'm okay with the 40 extra miles - sometimes it ends up saving you time in the long run. My sister just made the run and what shows as a 3 hour trip took them 4 (not towing anything). from my home to Beaver Stadium shows 2:45 with an unfriendly towing route so I am fine with an extra 40 miles of highway travel. I wanted to make that decision when we went to the LL World Series but opted to pull the hills and while I was fine temperature wise, it took the added time that I would have used on the interstate. Sounds like the same difference, but I just got the tune and that actually caused temps to spike again - the truck used to cut fuel due to temp which helped to keep temps down. I just put a bunch of money into the 96 burb so I need it to be my rig for a while. If only I could squeeze 6 kids and a hottie in a pick-up. They need to design a stacked car seat for little ones
I was a bit nervous for a while - which was why I started the thread. Now that a few decisions are made, I'm actually excited! LMK when you want to unload the Sierra - by then, maybe I'll be traveling with 6 (if you have the front bench) - lol.
