Where you score over the humble motorist in the [unlikely!] event of being intoximecated is that you are in a vehicle equiped for sleeping. If you are parked up and the TV is going and the kettle is on the boil it is hard for plod to prove you intend to drive anywhere, especially if you have a camper like mine which is undriveable when the overhead bunk is in the 'down' position.
No Kendall I don't know anybody who drives a 'dry' motorhome either, no guns here though thank goodness!
