That's a dang good website reference for RV driving. I'm saving that one!!!
I have a CDL-A so I freak out about this stuff faster than the average guy. I don't drive commercially anymore but do need to be a good boy to keep that CDL. I'll drive commercially part time in my retired years. Maybe!
Just fyi dodge is already using and has been using def on chassi cabs for at least the past 2 years. I think that they are using it already on the rest.
Also everybody else has had '13s out for 5-6 months- how come dodge still doesn't have numbers for thiers?
