It's highly unlikely there's a State Trooper on the planet who gives a rip how much an RV weighs, whether or not the TV is off while the RV's engine is running, or what the towing configuration happens to be. If empty, my guess would be the chance of being cited would be even more remote. Be aware too, that if you tow the dolly empty, it will tow much better if you lower the tire psi and if it has a steerable axle it should be locked out. My Demco SS directs the tire pressure be about 12 psi when towing empty. It will track better and won't bounce down the road behind you like a basketball.
