the 300 will do fine. if you have trailer brakes on the trailer you should get a brake controler. i have recently pulle 2 cars for a friend one was a dodge neon with a skid steer trailer and the other a honda crx with a homebuilt car trailer. pulled both no problem. i have a 3.08 gear ratio, i pulled the trailer empty at 2000rpm in 4th gear and with cars (basically no weight added) did about 2000rpm. got good milleage also.
