If your truck has a GVW of 7200 lbs you probably have the HD rear axle. The Differential will look different, wont' have the 2 notches the std. Gm axles do on the bottom at 5 and 7 o'clock.m This is a much stronger axle than the regular half ton axle.
The tranny is your other weak link- trailer only in Drive , NOT OverDrive ON THIS MODEL.
You have plenty of power with the 350 Vortec.

Thanks guy's - I should have it figured out tommorow morning. No tags, any more hint's on that glove box code???
The 3.73 is what I was hoping for - allows me 7500#'s - maybe I can still look at the Cig Bullet's.
Thanks. Bouy

Re: Gear Ratio - Chevy????
Front Side of the axel tube on tha passenger side is a series of numbers stamped into the housing that will tell you the gear ratio. You may have to "wire wheel" the area to see it as it usually gets covered up with grease & dirt, but it is there.... Ill try to find the link that will tell you & post it. Is for GM vehicles only.
This site will decifer all the GM "Spid Codes" located on the glove box door, & or the trunk lid of most cars> http://www.fl-thirdgen.org/rpo/rpo.html
This may work to decode the VIN of GM Truck, I know it works for cars for certain years. Tells you where it was built, etc....> www.nytmare.org/fiero/vin/decoder.htm

acccording to the sticker, the rear-end is a GU6 G80.
=
3.42 / limited slip posi.
OK - that puts me at 6500#'s
Gofastboater - thanks for the link, that helped alot.
Smitty, $750 would probably be worth it, thanks for the info and advice
