Just noticed your username is ED Lover, which reminds me of this guy:I think there is a lot of confusion about what a CDL is and when it applies. In the case of any RAM 1/2 ton, 3/4 ton, or 1 ton pickup the GVWR does not meet the threshold to require a CDL. The 10k pound rule people often quote applies to the trailer in the case that the pulling vehicle exceeds the GVWR requirement. It does not mean if you pull a trailer that weighs 10k pounds you need a CDL.
Thanks for breaking that down. Never knew what GVWR was.I think that your formula for payload needs some explanation, as I don't get it.
My understanding of payload is the following.
GVWR = total permissible weight of vehicle including driver, passengers, vehicle, options including trailer tongue weight.
Curb Weight = weight of vehicle with all fluids and gas. No load or occupants.
Payload = GVWR - Curb Weight - occupants
