Freightliner M2?

many factors effect handling....

for my type of equipment it depends on the setup and jifflock..

pulling doubles with a jifflock gets a bit ugly if the units do not track...

I know sometimes it is something as simple as air pressure in your steers - or minor allignment issues...

I assume your trucks are straight box trucks - and would then also assume that you may have allignment issues.

even new trucks need checked - see if your company will have it looked at by a reputable allignment shop.

 

Could be a problem with the air-ride (if so equipped); freightliners can get very touchy if the bags aren't filling correctly, or inflated completely. Latanea is right: bring the problem to your company's attention, and have them get it checked and fixed.

 

if he is driving a non cdl rig - then there will probably not be an air system... (no air brakes etc etc thus no air bags)

he states a 1 ton - dunno - one thing also could be too much unbalanced weight (side to side) or even so much on the tongue that hius steers are lifting...
