I have owned Weber grills all my life. I'm a charcoal grilling guy. Bought the 14"  portable Joe 10 years back for camping but too small when cooking for 4 people. So for years I put one of my 22" grills in the camper for our trips. Kind of a pain but it worked.
THEN the 18" Joe came along! So much versatility, quick to clean up and easily fits in the camp trailer. Thank You Weber!
