Around 1700 #'s w/ a 5 spd. w/ 3.73's , 2200 #'s with an auto for an '04 w 4.10's
I've never run into a problem towing up to 2000#'s with my 5spd, just leave room and brake early.
Max tongue weight on the bumper hitch is 200#'s anyway.
Gotta say, really appreciate having the 4 wire harness stock. Toyota wants almost $250 for the wiring.
