Since then I have had a number of opportunities to compare the mileage, driveability, etc with the Aerovault compared to a box trailer.

#1. No more spring bars and anti-sway to hook up. Just hook it to the hitch ball and drive.

#2. Driving with it, I can use the cruise control. Even at 75mph, I get about 13.5mpg vs. about 7.5mpg at that speed with the box trailer. At 65mph loaded I get 15mpg+ vs 9-11mpg with the box. When I drove the aerovault back from OC empty and slowed down for the speed cameras in Phoenix, I got 17.2mpg at 65mph over the flat windless 40miles crossing phoenix!

#3. Wind and handling. I had 40mph cross winds last weekend. You don't even notice them. The angled sides of the Aerovault may help this, I didn't even notice the wind. The truck gets blown around more than the trailer!

#4. Handling. Driving back from Taylor AZ to Phoenix You go from 7600' down to 1200' all of it in curvy 6% or better grades. Not a problem. Downshift the truck to 3rd or 4th and 65mph, utterly no drama. I was PASSING people! Rock stable, probably helped by the lower CG. This was NOT fun with the far heavier haulmark.
