I have a dodge 2002 2500 diesel with a 6 speed manual transmission. It is my understanding that there is a switch which can be installed to easily move from 4 wheel drive low to 2 wheel drive low for backing up ( to be used when backing up RV). Does anyone know anything about this?

 

I plan to do that here soon also.
