Thanks, all. This was actually my DIY build -- steel stud and hardiebacker with stone veneer and leathered granite countertops. Pretty happy with how it turned out.
Jim - I did go a little overboard with the vents ... original plan was one apiece for the grill, side burner and fridge, and one on each corner of the "L" (where I keep my propane tank) at top and bottom. However, after I added the hardiebacker/cabinet doors and hooked everything up, I would occasionally catch a faint whiff of propane when I opened the cabinet. Concerned me enough to get the large vent for the grill and double up my vents for the propane cabinet. Probably slight overkill, but better safe than sorry.
Fridge is marketed as an outdoor fridge, but I don't think it's technically "outdoor rated" since it was pretty cheap. It has an enclosed back to keep the critters out and more insulation than an ordinary dorm fridge -- keeps drinks in the mid to high 30s in 90+ weather -- but I wouldn't leave it fully exposed to the elements. I left it outside all last winter and it held up well. Made by Blaze. Pavilion is Amish-built, ceiling is just fir with mahogany stain.
