I bought 1oz and 2oz meatballs plus Marinara from Rest. Depot. I found some very nice fresh sub buns from Wal Mart. I fired up the cart and tossed in enough for Subs for me, the wife, and my F-I-L.
I put them on the left side of my cart just to see how long it will take to bring to temp- this side the pots sit above the water. It took an hour and 10 minutes to get to 165 deg. I will not use this side to heat, only to maintain. The right side directly over the flame will be my primary heater and it rocks so I'll transfer stock over to the left side(holding) once it's up to temp.
The product tasted great. My F-I-L suggested I use less sauce on the sub to ease the messy factor.

I did kind of pile it on! Pileing it on is a normal Son IN Law duty right?
The bun is a 9" bun. We are going to trim it to 6" and sell for $3.50. We will take the other 3" and sell it as a kids version for $2.00. Small kids won't be able to eat a whole one anyway and 9" is way to big. (Yes I ate a 9"er and I'm about to pop)
Cokes/Water for a buck, chips for a buck. Adult combo for $5.00.
Now , if only that hurricane would hurry up and get us wet before Friday night.
Thanks for everyone's advice. This will be my first official event with my new to me cart. I'll try to remember to take my camera.
Lets ROLL!
