Refill Propane vs Exchange

When I asked him about it he told me that the cost of getting the required licence and the cost of the liability insurance was prohibitive as he simply did not sell enough to justify the cost.

This concerns me that it might be an indication of where the industry is going.

Also I bought a small 10 lb tank for my BBQ. Those are not available at exchange locations.

Hardly an issue, especially if your trailer has dual tanks. That 10 pounder you have can also be used a spare and 16 oz canisters, 'though expensive, are readily available just about anywhere. Carry a "2nd Chance" or "steak saver" adapter and you can even use one to run your camper in a pinch. No way I'd waste $$ on way overpriced, typically underfilled propane exchange tanks when here in Ontario Costco's propane pricing for refills is so inexpensive, about $12 Cdn at the moment for a 20 lb fill.
