Good for you!
Did you buy the front shelf?
Is the grate in zone 1 still cast iron?
Now that the wheel-set has changed from my 2013 unit, how easy is it to roll around?
The front will stain from smoke leakage. I recently cleaned mine rather thoroughly and treated it with TopCoat F-11, an automobile paint treatment. It makes it much easier to wipe clean. If I bought a new stainless steel pit I'd give it two or three coats of F-11 before I fired it up for the first time.
I also wouldn't bother seasoning it. My seasoning just builds up until it flakes off. Seasoning doesn't stick to SS as well as it does to mild steel. Just do a burn-in to remove manufacturing residue and start cooking.
