Trailer smoker build

Thanks for the nice comments guys! Just picked up 4 pieces of sheet metal, shown below (two mild and two stainless). My son is inspecting:thumb: We're planning to use the stainless sheets for a 6' long storage bin which also double as a short term cooler, when we transport whole pigs. We'll lay the mild sheets down on the base of the trailer. Also picked up a sink from neighbor that we'll install at some point. I'm curious if anyone has any tips on what else to add to the trailer. We'll add a work table on the front of the cooker at some point. Anything else we're missing? Thanks for any ideas you guys have.
