I think I'm finally going to make the switch from electric to propane. My Old Smokey has worked well...but it's limited. I think I have narrowed it down to either a GOSM Big Block or a 24" Smoke Vault. From reports sounds like I can't go wrong with either. Also should I expect a better bark with gas? And has anyone made the modifications to fill their 20 lb. lp tank from their larger home tank? Thanks
