Haven't posted in awhile

Hi All,

I sold my last square body about 3 years ago and haven't been around the website much. Mostly because my oldest car now is my 1991 Chevy Van. Haha.

But I thought I would share my 2006 GMC 4.8L 4x4 with (I think 3:42 gears) that is my daily driver. I've never really posted about it because I mostly use it to haul my camper. Which brings me to the reason for this post.

Can anyone tell me what are the best choices I could make as far as making this thing tow better? I'm sure most of you will say "drop in 5.3", but that is not an option for me right now. Should I re-gear the axles to 3:73? I figure that's a couple grand at least. Would I have to change anything with the computer?

I've read about Black Bear Performance and maybe I could have them re-program my computer for more performance? Thoughts?

Anyways, here are some pics so you can see what I am working with. Truck has 138,xxx original miles. I believe I am the 2nd owner and truck extremely well cared for by first owner.

Thanks!
