Thanks everyone for the info. I have researched it as far as BTUs and such, but even if it put out as many BTUs as the sun, it is useless if it don't work. I was curious about the reliability of it. As far as the number of people I am going to feed, I hope everyone in the county wants to come buy some of my food. I cook regularly for 60 to 100 people at my brothers party barn, but these festivals/fairs/car shows are new to me. I intend on using this grill a great deal. I happen to be making fajitas at this 1st event, so I need griddles.As far as the griddle plates, they are available from the parts supplier. Stainless steel with 3 inch tall sides, and 2 of them will almost cover the grill completely. $59 bucks each if I remember right, although, the fabricator in my is telling me to make it myself. We'll see what happens. I will post pictures when I get it, and of what ever I decide to do for a griddle.
By the way, I took left over fajitas to work today, ( I was having a practice run) and I was informed that they were going to take orders from within the plant (and take up money) for me to cook fajitas for everyone else that wants them. I happened to give the maintenance secretary a fajita, and that was her idea. She takes care of us maintenance men. I dread her retiring in a few months.
