Where are you putting the wood/charcoal? Anyplace to store supplies, tables and misc items like a shovel on the trailer? You have flip shelves in mind? Maybe stabilizer jacks on the corners to level it up? Definitely a cool idea tho, should be able to cook for a pretty big group on that.
It doesn't take much steel to get to 1500 pounds...be careful.
Thanks dirtytire, mayby I sgould leave the bricks on thebside walls to have less weight. If I do that ,I´m more able to make some air vents on the side off the trailer. All the gear( shovel, charcoal etc) will be transported by car/truck/bus....another option is to make the sheet metal from the actual grill thinner. I preserved 1/4 sheet but maybe 1/8 is also an option. Or will that be to thin?
If you leave out the brick you'll want to insulate the area between the tires and the fire box to keep your tires cool. Take all the brick and other supplies you are going to make the trailer out of and stack them on the trailer..see how it takes the weight of all the raw materials then you'll know what it can take.
I would think 0.125 should give you an acceptable lifespan for an open fire like that. I just did a quick check on a high-end manufacture of chicken cookers and top grills. They only use 13g (0.09375). Obviously, thicker will last longer but weight, cost and use must also be considered.
Rust is going to be your biggest enemy anyway. Make it easy to clean (every last bit of) the ash out and it will last twice as long. Some sort of drain holes for rain would help prevent standing water and slow down the rust as well.
Realy appreciate your input guys!
Made up my mind and decided to stay with the 0.250 sheet metal, only heat resistant bricks on the floor, insulation all around (2 inch thick), and extra air vents on each side( not yet on the drawing) . Figuring out to coat the .25 sheet metal couple of times with heat resistant coating and some oil. The tip about extra drainholes is more then great!!! Thinking about putting 2 of them in.
Hi guys, as you probably noticed, plans change here a lot....my client had other ideas picked up so after some drawing and thinking I came up with this.
As pictures say more....a double santa maria, asado cross, dutch oven hookup systel, extra grill and tepanyaki plates.
