I saw a couple common misconceptions here I just wanted to touch on. First is tow rating. That weight they use is for a base model truck with close to zero options. The big number is the GCVWR. This is the weight of the truck and trailer combined. They take this number, and subtract the weight of the truck to determine the tow weight rating. They also use a 160lb driver. If you weigh more than that you have to subtract that from the tow rating, if you put stuff in the truck you have to subtract that from the tow rating etc. You would be surprised how little your fully optioned, packed for the week, carrying your three buddies SUV is actually able to tow.
The second is pulling power. I have no doubt a half ton could pull my jeep, my boat, and my camper. It's the stopping that worries me. 3/4 and 1 ton trucks have bigger brakes, they also have bigger everything. Would you wheel your jeep stock? Probably not as it would most likely break even though it is "trail rated". You upgrade everything to make it last longer, and make it stronger. The same applies to towing rigs.
