> BMW X3 is a small SUV and I think it is rated for 750 kg unbraked and 2,400 kg braked (up to 12% slope) total trailer weight Good context here! Our truck has a listed towing capacity of 12,500# - 5,670 kg. My dad and I are driving ~90mi tomorrow each way to pick up an inline bale trailer he just bought. We checked hay prices in that area, and they're cheaper than what we can buy locally - enough cheaper that we bought eight bales to bring back with us. Each bale is ~1,200# (+/- ~200#), for a combined load weight of 9,600#. The trailer weighs 2,700#, so we'll be towing ~12,300#. The truck itself is another ~7,000#, and by the time you figure in fuel and occupants, we'll have a GCWR of right at 20,000#. In short, tomorrow I'll be driving that truck and responsible for TEN TONS going down the road. The BMW X3 would have to make four trips hauling two bales each: 2,400 kg = 5,290#; the trailer weighs 2,700#, two bales weigh 2,400#, leaving only 190# of excess capacity. Even then, there's no way I'd be comfortable driving an X3 with that much weigh, that distance - and that's not even considering that the trailer is a gooseneck. I think of the truck as ~1/4 of a semi tractor. We can haul most things ourselves, more cheaply and with less environmental impact than hiring a professional hauler.
