Still a lot of variables; which width and sidewall height you have? I have a 26' Dakota that is 102" wide and 72" side wall that you need good heavy corn and stuff every corner of it to get 750 on it. Could have got 80" sides but its hard enough to see over the side unloading cart the way it is. The short trailer is nice for inexperienced help turning in field driveways. Got a truck with a C-12 and Autoshift pulling it and it is sized about right for the tractor anyway. And its only legal to 69'000 lbs anyway.
