Very nicely done, Brad!
I thought about building my own cart but before I found the roundtuit I found a used Performer. One of the greatest features of the Performer, IMO, is the lid holder. You might want to consider making arrangement for hanging the lid off the backside when you're cooking.
Have you decided on the SS yet?
Congratulations. I'm envious of your ability.
Surprised there hasn't been a kick starter campaign for a unit that someone could assemble. You'd think there would be a nice market for one considering how much of a price swing there is between a OKP and a Performer.
HOLY CHIT! That is the best cart I have ever seen! Marty you are truly an artist.
