While newly manufactured propane tanks do need to be purged of air before their first use, and many refilling locations (not specialty propane businesses) might not purge them, this is no longer a concern as the tanks (apparently including those from Escape) come from the factory ready to go; they're "vacuum purged".

Just for clarity... they all have floats now, to run the Overfill Prevention Device (OPD); what you need are tanks equipped to use that same float to run a gauge.
Since you can get gauge-equipped tanks at all major retailers of propane tanks, you can get them anywhere, presumably including in the Chilliwack area. I've seen them at Canadian Tire, Walmart, and Costco... but sometimes Costco only has tanks without the gauge. I'm sure they're cheaper in any major U.S. city than anywhere in Canada, but if you're short of space in the tug with all your trailer stuff in it for the pickup trip, you don't need to squeeze in two five-gallon tanks. Maybe this isn't a concern, with a pickup truck.
I think Escape's base pricing includes the propane tanks, but not the propane. If you have the space to carry extra tanks, you could bring tanks with level gauges, get only those ones filled, and safely carry the empty tanks (that come on the trailer) with you as spares.
