My Outback has a grill that attaches to the rear bumper and runs off the trailer gas…as does a two burner stove top. The grill works great, really no need to cook everything at the speed of light. I know how long a nice thick steak needs to cook at medium between flips…nothing wrong with the little guys, you just cannot expect it to cook the same way the one at the house does…
I had an RVQ on a Fleetwood trailer that was used every day when I full timed…same thing there, lots of complaints, because it did not meet folk's expectations when compared to their home grill, but IMHO, that is like comparing apples and oranges.
