I monitor a number of RV forums and when I see someone asking about tires, I will make the effort to learn about the problem and offer possible solution.
Recently there was a question on inflation for both the TV and the TT. The comments seemed to be all over the place so I decided there was a need for some basic foundation of information needed. Following is my reply and attempt to provide the basic information needed by RV owners.
A few days later the following was added to the Forum thread
"------------------ Steer Axle ---Drive Axle --- Trailer
Weight #1 - Truck only/hitch/bars -- 3180 3520 (exceeds 6500 GVWR)
Weight #2 - Truck and Trailer with WDH bars -- 2980 4320 4880 "
