NO!! Do NOT put air in there!!
With the right mixture of air and propane, you'll have a bomb. (Difficult to set off, but never the less a bomb ... or at least, a torch wherever it leaks.)
Plus, any reputable propane refill place would have to purge the tank before refilling it.
I use a propane dealer/distributor to have my tanks refilled ... costs less than the bottle swap-out places. They also know the regulations and can check your tank for you, as well as replacing out-of-date or questionable fittings. Many can also do leak-down tests to check the whole system. They have special tools and techniques for testing ... involves pressurizing the system, closing the valve, and waiting a bit to see if pressure drops.
When I had the system in my cabin checked, they tried to hire me based on my installation. (I've worked with propane installations and know what I'm doing, but don't have the certifications.) They insisted on testing before renting me a permanent tank.
Having them test the system eliminates having to crawl around yourself. Also, they test the system to protect their liability so they typically do it free of charge.
Compartment is the main issue for changing from permanent tank to bottles. DOT has definite regulations regarding the compartments, as well as permanent tanks on vehicles.
Re-certifying tanks requires training and government certification and most reliable places won't go near a tank unless it's certified.
Enough for now, I just woke up and am caffeine deficient.
