Kenny,
I LOVE my Tahoe, but if given a choice, I'd stick with the Burb. I have a very similar set of trucks - the Burb has 97K, the Tahoe is close to 180K, so it's pretty close to what you've got.
If I HAD to pick one, I'd keep the Burb. Why?
1) Everyone fits comfortably, and if you have more kids, they will fit as well.
2) It is a LOT better towing due to longer wheelbase
3) It has 75K less miles
4) It has F programming and no stupid EGR or low CFM intake manifold.
5) Better cooling system.
6) Newer, tighter.
7) AWESOME for road trips. It really really is. It can cruise all day long at speed without breaking a sweat. Getting one with around 100K miles is almost unheard of!
8) Massive storage capacity. You really can go camping with the family and have room for it all.
9) Not a big difference in fuel economy.
10) Two air bags. God forbid you ever use them, but hey, you have 2 now.
11) Something new to work on, that has a younger engine!
Yes, the Tahoe is loads and loads of fun, but if you can only keep 1 of them, get the burb. Put sway bars on, a decent set of tires, and a big exhaust, and you'll like it just fine.
Good luck, buddy.
