Thanks for all the welcomes and info so far, I've definitely learned a lot from this site.

The codes in the glovebox don't show a limited slip rear, and from the snow and ice I've been on so far I don't think there's one in there, but I guess I'll see for sure when I open the rear diff.

I also was able to do a vehicle history report and found that it definitely has over 100k miles on it.

Dash is not cracked other than a couple small ones over the speakers between the little holes there. Should I be looking for a cover for it to keep it from cracking or does this happen when people are taking it off and putting it back on again?

that is a sweet burb.....before you jump on the changing of gears part ,you need to do the math and see where your at...im not against changing gears for benefit...but ive seen people go from say 3.42 to 3.73 only fuss about it later....thats to close on ratios and isn't much diff than a new set vs worn out set of tires.....sometimes it takes a big jump to get you to the sweet spot you need to be....

with 33" tires and 3.42s at 80mph with od gear of .7 (guessing)...you would be turning around 1950rpm at 80mph....at 60mph your only turning 1463rpm

at 80mph with other gears it would be..
3.73=2127rpm
4.10=2338rpm
4.56=2600rpm

I'm tell'n ya....4.56 with the overdrive. That low of an RPM kicks the converter in and out and lugs the engine. Small blocks seem to be happy cruising at 2200-2500 rpm. I'll be running 285/75r-16s which come in at about 32'' tall

Well it has 4.10 gear ratio. I'm sure 4.56 would be a little better but probably not enough to be worth it for me to do now.

My Suburban is also my daily driver and I put around 50k miles on it each year. What I can tell you is that they are not made for high speeds especially when lifted and 4 wheel drive While I've got the powerplant and gearing to go into the triple digits, I find it much more relaxing and safer to drive slower. 65 mph seems to be the sweet spot and once you start exceeding it, fuel economy plunges quickly due to aerodynamics.
