I noticed some of the new outdoor kitchen models come with a stand that ubolts to the rear bumper, for a grill, that swings out. They also will come with the sidekick grill. I called my Keystone dealer and bought that stand (pricy $180). But I bought the Olympian 5500 stainless grill. I believe it has 180" of cook top and at 12000 btu's. I bought it, cause it hooks into my quick disconnect propane fitting for my outside stove(its meant for low pressure). Just got both Sat, so the next trip I will comment on how it works, and take some pics.
I have a roadtrip also but its too big and a mess to cleanup.
