I have a gen 1 Loco 36 inch griddle and the surface temps vary wildly so I am looking to replace it. I am leaning toward the Traeger Flatrock or the Halo 4b. I am having a plumber check to see if its viable running NG to my griddle location, so that answer may sway me further to the Halo. I have read some people say the Halo 4B gets too hot but others say its fantastic. Hard to find anyone complaining about the Traeger though. Any suggestions? Thanks
