I went to a website a while back for I think a Brother and they had one of those enclosed car trailers and they had installed 2 big commercial sinks, had a refregerator in there that was anchored to the floor, cabinets and a ramp on the back to roll out the smokers. Had a roof air AC unit and they had a side door that they used those heavy plastic panels like they have in the big coolers so the fork lifts can go in and out. That way they could come and go and not worry about bugs and letting out all the cool in the hot summer. The inside also doubeled as a place to sleep and they would just set up cots. You can buy those units pretty cheap and if you keep your eves open, you can sometimes hit an auction for a defunked resturant and pick up the sinks and counters pretty resonable. When the PB and I retire, that's what I'm gonna do. Pull that puppy behind the motorhome.
