As some of you know I purchased a garn 1500 to heat my home for next year. I just got the opportunity to purchase a 500 gallon propane tank for $50. That got me wondering if anyone has added storage to a garn or not. Not saying I'm going to need more storage but I'm not going to pass up the tank for $50. I tried to search but couldn't come up with anything with the garns. Thanks guys!
