I was able to modify the grill to use my RV supply line.  I wish Weber made and supported the conversion for RV supply lines.  There are many people that buy and modify the Weber Q series grills.  It is a good grill and easily modified.  I've been on a 2 month trip and the grill has been great.  Many campgrounds out west have charcoal restrictions.  So, a gas grill is a must for grilling.
