[5.0 Junkie]

Trailer axles weighed right around 7500# while hooked to truck. I just went over truck scales. Truck axles together were right at 8300#.

I am a Heavy Duty Equipment Specialist for Hunter Engineering. Needless to say, truck is aligned perfectly and tires were done on the latest balancer. They also had relatively low runout.

I drive around 65 most of the time. I have recently installed a custom tuned chip with a 60hp tow tune. Mileage is now around 9.5 most of the time. Chip helped some and slowing down a bit helped some too. The 7.3l gets decent mileage under 2000rpm, or 66mph or so. Above that and it starts dropping quickly.

I'm going to skirt the fenders on the trailer soon. I'm likely going to put on airtabs just to calm the trailer down. It is quite a handfull in windy conditions or around a large truck. I have a boattail design in my head and a framework to help out the front of the trailer. I am also trying to find the fringe material or similar to put on the lower edges of the trailer to see if that helps some.

I have a weight distribution hitch with 1 sway control. It is set up per instructions. What setup were you referring too and how would one of those other hitches help over what I have?
