We have a BH 3010RE and there is no external auxiliary gas line to connect to a portable BBQ. We currently travel with a Weber portable, and use a 20# tank with an extension hose to avoid using the one pound disposable cylinders. I was wondering if there is a safe and practical way to tee off of the RV 30# tanks and use the BBQ with an extension line run from them instead of lugging around the 20# tank. I don't want to do this if it might compromise the safety or operation of any of the on-board RV appliances, but was thinking that if there was no problem, it might be a good way of hooking up the BBQ. Any thoughts?
