Thanks everyone for the kudos.
Sean, That is a digital voltage meter to monitor battery voltage. I got it off e-bay but the instructions are not clear on how to hook it up. I'll figure it out someday.
Joanne, The table worked great. I was able to cook with two DO's at once and it held up fine. I do wish I had make the wind screens taller, but I was using the left over from the bottom. I can also put my stove or BBQ on it. Also my cooler fits perfectly under it.
