Be aware the tow rating of your tow vehicle is one of two numbers.
ONE is the rating of the hitch. The other is the difference between the tow vehicle's loaded, full fuel tank weight and the maximum combined gross vehicle weight rating of the tow vehicle (This is different from the max GVW, higher, that additional "C" in there counts the trailer.
Whichever of those numbers is lower (MCGVW-GVW) (note the dropping of the M in the second term) or the Hitch rating, the lower number is your tow limit.
