I'm thinking of cutting a slot in a galvanised garbage can and setting the burner and pot inside for a wind break, you can still watch it like a hawk & all the gas controls are on the outside. took me over an hour to heat it up to 325 degrees on thanksgiving, I like 350 better but didn't have the patience. I use an italian dressing marinade to inject the turkey, have to be careful of the size of the particles in the dressing as they will clog the injector. I also went 3.5 mins per lb, even though I can't eat it I don't want to get the family sick! (well not all of them anyway!)
Beer helps but not too much, when you immerse the bird do so slowly, watching how it bubbles. it took me at least 3 min to fully immerse the bird on thanksgiving.
good luck
