Teberd, I aint trying to start nuttin but totally loaded that rig aint gonna hit 5000 pounds, no where near. If my research the rig before the motor wont be but 1600 pounds, motor may reach 700, 4 batts 400, gear just say 1000, thats only 3700 pounds and I bet this is way heavier than it will actually be. I agree, I like tandem axle trailers, have pulled both all over the southeast but for the most part it is for the braking, seems to work better on a tandem axle trailer.
