we have a 268 searay weekender. We would like to add a gas grill to the boat. No must i use one of those stainless gas grill setups. Or can i use a regular gas grill? I would get the stainless mounting bracket and use a 30lb propane tank located in my midberth storage compartment and run a special gas line from the propane tank to the grill when it's in use.Just can't c spending 400 bucks for one of those boat gas grills esp when they look no different then a regular gas grill
