The trailer is 250 kg (551lb), the sled is about the same wet.
~1200kg (2645lb) is the limit i can pull with this hitch (legaly), but with te bigger trailer, 3 sleds, clohing, packing, gas and whatnot, i gues i´m howling about 1500kg(3307lb) sometimes.
2½" radiator helps with the cooling, but as you say, a car and cartrailer would be heavier.
