I tow a dual axle trailer (10k rated) with a mini excavator (estimate 7500 total), or a 24ft camper (about 8000) with no problems. Make sure the trailer brakes work.
Mine is sigle wheel with an auto, some pump tweaks and an egt guage, I max at 1200 on long uphill grades but it comes right back down and settles around 8-900 when towing on the flat.
