Spread axle end dump vs tri axle end dump - Bulk Trucking Forum & Discussion Board & Bulkloads.com

I am looking at 2 end dumps. One is a spread axle full frame and 39' long and one is a tri axle full frame(front axle lifts) 35' long. What would be a better set up? I understand there woul dbe some tire dragging with the spead axle, but other than that what would be a better set up?

Thanks
