I live in and am licensed in AZ and regularly tow a 15,000 lb RV trailer through CA, a state that requires a non commercial class A for towing a trailer over 10,000 lbs. I've been stopped but never ticketed because the state where I am licensed does not offer a non commercial class A and does not require any additional endorsements to drive or tow any recreational vehicle. They cannot ticket you for not having a license that is not available to obtain in your state.Be careful with camper size pulling behind a truck. If they are above a certain weight limit you will be required to have at minimum a class A non cdl license. I had to drive to Ohio and bring my buddies truck and camper back to pa and it ruined his hunting trip.
