owners of 3010ds and 3011ds how does your rig drive?
Ok, here's my experience with a 2012 3010ds. I carefully check the air pressure. Running 80 psi rear and 75 fronts. I also work on balancing the weight side to side. At 5000 miles I had the rig front end aligned. Amazing difference. I also run 65 psi in the air bags. A truck shop did my alignment in Delaware Ohio. Very good folks.
I have zero and I mean zero problems with semi's or large trucks. Believe it or not I will get a slight push from a full sized pickup or van only traveling in the same direction but nothing from a large truck in either direction.
It handles very well and I'm very happy driving it at whatever speed.
Tire inflation, air bag pressure which transfers some weight to the front axle, and front end alignment are the keys.
