Do you have to have a special driver's license?

I like they way a simple question about something on here leads to discussion of why chickens have feathers and geese don't, but for the OP's question on his license. Yes, in Kansas they require a non-commercial license for a vehicle with a CGVWR over 26,001 lbs. However, this is not a CDL. RV's do not require CDL (commercial driver's license) unless you are one of the people that deliver them from the manufacturer or if you are getting paid $$ to transport them. Besides that if you are legal in your state, the states that you visit while travelling you are legal as well.
