Not sure that I would want to "lock" myself in to grilling right on the side of my camper. For about the same price, I bought a Weber Q220. The housing is completely cast aluminum (no rust), the cooking grill is cast iron, and the burner is stainless steel. I feel the thing will outlast most grills in this price range and Weber makes a quality product. Also since we are empty nesters now, I went with the larger Q220 (versus 200 or 120, etc) because it is also our main grill at home now. I found the optional cart/stand at Camping World for $35 (normally $50) and I also bought the adapter hose, so at home I keep it on a 20lb LP tank and just use the small, disposable LP tanks when camping. This gives me the option to leave the cart in the camper and just set the Q220 on a picnic table at the campsite, or put it on the cart and roll it to where I want to cook. I have had times where it is windy while camping and I will roll my grill down wind of the camper and use the camper as a wind block. Personally, I would not want to have to have my grill in a fixed location right next to the camper. Especially under the awning, where I tend to keep a lot of other things out of the weather, including sometimes my motorcycle.
That's my 2 cents... the one benefit would be you would be cooking with the main LP tanks on the camper, so you wouldn't have to deal with the smal, disposablel LP tanks.
