What determines what towing capacity of a vehicle is?

i currently own a 02 s10 crewcab 4x4, with a tired 4.3. ive towed plenty with it before, with no issues, but i think its time to do a few upgrades.

i will be blowing the truck apart soon, ls swapping it, rebuilding the trans, adding aux coolers for oil and trans. also most likely big brakes, with trailer brake controller. i will be upgrading the rear springs at the same time to a bit heavier duty springs. i currently have a load leveler trailer hitch also.

so i guess the question again is, what says how much i can tow, besides my tow hitch, and owners manual.

in a hypothetical world, would i be able to have a fifth wheel with say a 2 car trailer? or would my truck just buckle under the pressure.

i know i could easily go buy a truck to tow. but i like my big lil truck. i can park anywhere, its comfortable, paid for.

what are your thoughts?
