On propane refills, I don't know how it is along that route in BC, but here on the Island it is hard to find a place that will do the big tank in the MH. Local knowledge is required. Lots of places refill or exchange propane bottles of course. (not so many that refill, more that do exchanges)
EG, AFAIK there is only one place here in Greater Victoria that does the big MH tanks. There is a gas station in Parksville that does. There are other places up-Island probably.
I would confirm ahead of time for trip planning just where exactly you can get the MH big tank refilled along the way.
In a thread about this recently, it came out that the big tank in our MH is equivalent to approx. two and a half 30 lb bottles, but size of tank varies among MHs--smaller in smaller MHs most likely.
