I have a 2011 travel trailer 22ft and a 2003 expler 4.6 class three hitch with trailer tow do i use overdrive all the way to my destination or not .thanks
FWIW, my long term mechanic told me to never tow my trailer without first locking out OD with the trailer mode switch. I have followed his advice, even with my new Silverado. I agree, check the manual.
