Yes, this was Friday nights meal, so before the sliders. I have an adapter, basically the opposite for my my Lil buddy heater to hook a big tank too it. My son has the Blackstone 17" that is setup for the 1 pounder bottles, but got the adapter to run on the big tanks also! Either way it they can and have saved a meal or 2!
I have that adapter, too with a 6" hose with the 1" disposable connections.
I have a slide in truck camper with a horizontal 20 #er that most places don't like to fill as it doesn't have OFP and they're not exempt anymore. I attach the steak saver to the camper whip hose, use the 6' hose to connect to the 30 #er on the ground with the otherway adapter.
Should just get a 6' whip hose, but don't use the camper much anymore. The new approved horizontals don't fit in the cubby.
I use that hose, filter, and adapter on my buddy heater or my Blackstone or my old Coleman Roadtrip grill. Use the filter. Buddy (pun intended) learned the hard way that an older hose will plug the orifice on the heater or other gas appliance.
