I threw away the grill that came with our 21FBRS and bought the Richman Traveler at Costco. Built like a tank, all quality stainless and cooks good, no actually great! The only problem it that it is quite heavy, over 50#, and somewhat large. Will not fit in our storage area.
I think we will use it on our deck and purchase the Napoleon TravelPro 285.
Less than 30#, about 2/3 the grill area, and smaller overall, more suitable for RV life. Those that have them rave about their cooking ability, most say better than Webber Q 2200...and that's saying a lot!. I don't know about the other 285 models, and only have had excellent reports on the PRO285.
