No way a 2017 Freedom Express 192RBS will be stickered at just 3798 lbs when my own 2014 version is 3815 lbs, as newer models are much porkier than my '14. Towing with no water in the water heater tank and fresh water holding tank is unrealistic as that means the system would have to be repressurized and purged of air each time you wanted to use the system AND you'd lose the ability to use the system enroute. The 192 comes with two 20 lb propane tanks, each of which will eventually contain 20 lbs of propane gas. Most vehicle manufacturers include the weight of a full tank of gas in what they refer to as the curb weight of the vehicle ... you really need to weigh your Lexus with a full tank of gas because until you do you're just guessing.
