I don't pull much more than 1500 Pounds with mine, I'm generally nice to her when pulling something BUT, with my buddies 03 ranger, 2.5L ??Gears I have hauled half a CuYd in the bed (scraping pavement!) we have pulled a 16 foot Lund with the bed packed with gear from Central MN to International falls, weight unknown. and NOW for the true abuse... In his old 96 Ranger, we would regularly pull a small bobcat on a bobcat trailer around town, but not on a highway, max about 30-35 MPH and on RARE occasions we have pulled his 970 bobcat around town but never more than 20-25 MPH (if not more like 15!) I know the 970 weighs in at just under 10K so with the trailer figure about 11K or so. The handeling was like dancing with an old pregnant Sow, but the lil champ pulled just about anything we could load on a trailer!
My brother knows about that pig dancing stuff, thats also a WHOLE other story though! hehe)
