Maybe its the proper cooking technique?
As far as the grill, the RVQ is a hotter running rig in itself. I trim the meat well I do keep some fat on the steaks and cook the burgers with that are 75% lean. For burgers you should turn the heat down so it does not cook the outside so fast and keep the inside red.
The grill is about 5-6 feet below the awning (estimated) for my rig and that may be the difference. I have yet to see anyone with one of these grills document the grease buildup and heat issues that have been discussed. :h
