I don't have any pics handy of my comp sink setup... But for something permenant on a trailer, for my catering setup, I took a 6' stainless steel work table, got a double stainless sink and 2 single bay sinks out of old campers, mounted them in the table (wash, rinse, sanitize, and hand washing), mounted a 21 gallon fresh water tank, water heater, and pump all on the bottom shelf, and use a portable waste water tank with wheels that rolls under the trailer when set up. Works great, and have less than 400 bucks in the whole setup,, I'll try to get some pics of it posted.
