When I worked at Derrick Co. I had to fill all the proane for the forklifts, and whatnot. I also had to fill a few of the 100lb tanks, which were a pain in the ass to put on the scale then back in the cabinets. Good workout though.
That is what I have, with a BroilMaster Grill. I wanted to upgrade a few of the things on it but it has been great, now I just need a smoker and a charcoal grill.
