I stated automatic, above, but I meant std.
if your truck is a 4x4 (2wd can pull more) and is a standard (autos can pull more), and has 3.73 gearing (4.10's can pull more) then the max weight of your trailer shouldn't exceed 8650 pounds. the other thing to consider is what we call your GCVWR or Gross Combined Vehicle Weight rating, They call it the GCW and it shouldn't exceed 15 000
pounds (note, this is the "scaled weight, or all your gas, people, cargo, etc.
Again, these numbers are for a 4x4 HEMI QCLB with a standard transmission, and 3.73 gears. (in other words, the lighgtest duty 3/4 ton you can spec).
