I have both the 17 and 22 in. 17 stays in trailer and 22 at home. No rust on either. We cook everything on it. Don't even bring the bbq any more. With a pizza stone and cover we even make pizza. 22 in. at Walmart with stand, cover and propane hose is a great deal at $147. I like the 22 in. since it has two burners so you can have a hot side and a "hold"(cooler) side if you want. The stand fits the 17 in. as well.
Easy to convert to quick connect with torjik kit.
