Those tow guides are way too general.
According to them I should be able to to a lot more - once I got the owners manual I got the details...
You have the tow figure but also a GCWR figure and you need to consider both - as the max tow assumes a nearly empty TV, so as you add passengers, cargo, the hitch you can eat up 1000lbs of your tow capacity.
One figure I came across says my truck can tow 9000 lbs, but the GCWR is 12,500 (it's 13,500 for a 2wd with 16" rims). Take 12,500 less the ~5800 the truck weights and you get a max tow capacity of 6700lbs. WAY different than 9000! And it's something you dont' find out until you own the truck.
4x4 costs tow capacity as do options on the vehicle as these things reduce the GCWR. The 17" rims on my truck cost 500lbs in GCWR over 16" rims. Not sure the reasons for it - more weight or a change in gearing or something else. I assume, but cannot find for sure, if the third row bench seat is included in the vehicle's ratings. Mine is removable and and it's out so that cuts 75lbs or so off my load. There is also a note in my manual about the max frontal area of a trailer as well (60 or 64 sf as I recall).
So the 9000 rating gets small fast. I added up the trailer (5400lbs) the truck (5800), people (600), batt/propane/hitch (200) and I'm at 12,000 lbs. Add in food/clothing/cargo and I"m no doubt at the 12,500 gcwr with only a 5400lb trailer!
