I have the exact set up got it a couple weeks ago after only 35 years of marital bliss. You're way ahead of the game. I have used mine with split fire box and whole, makes it very versatile. It holds temp forever. To stay between 225 and 250 I have to completely close the bottom and barely crack the top. Got it over 600 in about 45 minutes too. The SS cart is quite sturdy and good thing since it's 200 pounds. Have lots of help setting the cooker down in the cart, it took me and three young bucks to load mine. All I still need is a cover. You'll live it. And good luck on what must be upcoming nuptials.
