I finally decided on a grill. I got a 41" Viking with TruSear infrared. I was going to do the 53", but then someone mentioned that you really only need that much space once in a while. Since you really need to use all the burners every time you turn the grill on (to make sure the grill heats properly) it would be a huge waste of gas to get the 53". I also looked at a DCS, but they drop down to a 36" from thei 48", and that's just too small.
I got the natural gas version. They're installing the line this week and the grill comes on Friday. I can't wait to see how it compares to my old Weber (which I love). Supposedly with the Trusear you can do some amazing stuff... sear the outside of steaks while the inside stays rare... same thing with tuna... should be fun.
Closed:
Open (I didn't get the side burners - just couldn't figure out what I would ever use them for):
