2012 Towing GuideIs your truck a standard cab, extended cab, or crew cab?
2X4 or 4X4?
What axle ratio? The code can be found on the build sticker on the glove box door. Look for the code(s) beginning with "G" and either post them here or Google them.
Now find your tow rating but that's the minor part of the equation.
On the driver's door jamb there will be a yellow sticker with the payload rating. This is NOT the weight of trailer you can tow, that's the GCWR (Gross Combined Weight Rating.)
Figure that trailer will gross out at 5700# or so with a 800-900# tongue weight. Now add the hitch, passengers, and gear to that and see if you're over the 7000# limit.
And even if you make it under the weight limit the 4.8 is a bit anemic for towing.
