Yes LP tank, I have a ferral gas co that seems to always have 250's and 500 gal tanks available. 500 is pretty big, I have a friend that has 2 500 gal lp tank cookers on seperate trailers and holy cow they can handle a ton of meat. I think he told me that they have put 3 hogs on one cooker before without any issue.
I realize that since it will be on a trailer anyway why not go 500 but I really don't think that I need one that big and that is the reason I switched to the 250 idea from the 120 gal tank.
I think that 30 wide and 84 ish inches long will be plenty big enough for what I am going to cook. Looking for enough room to cook what is needed for a contest or two with out having to use another smoker to cook enough meat (2 butts, 2 briskets, chicken, ribs, chicken wings, and sausages) all at once.
I will add a warming box above the fire box as well as a water tank so I can have hot water for cleaning up and such.
So right now I am scrounging up materials needed so when hunting season is over I can start to build this cooker. As well as picking up add ideas to incrporate into the trailer/cooker.
BTW - this cooker will be have a theam, It is going to be my tailgater set up in Minnesota Viking colors, it will have viking battle axes for door handles, painted purple and gold with viking logos on the ends, flag pole, horns, chrome "Minnesota Vikings" in about 3 or 4 foot long words mounted on the back side of the smoker...and probably a few other things if I come up with them.
OH yeah a friend said that he will make me a dig thermometer that will have a electronic secondary switch that when I hit the preset internal temperature from the probe it will trigger off a relay that will sound off the horn "the viking horn" that sounds off when the vikings score a touchdown during their games. just need to find the best way to develope the horn. Wish me luck on this one.
Trying to find a purple and gold high temp paint...
