I'm pulling
@Junkyarddog 48' spread this week with 60' pipe.
About 28 on the drives and 38 according to his rightway on the trailer. The way this Volvo loads, I'm 12500 all the time on the steer axle. And I'm centered on the tandem for the kingpin. I don't think weight will really change much sliding.
Makes life interesting.
So I feel with you on the loading.
