Check how long you need to leave for before re-entry - a month in Squamish/ Bugaboos might do it.
A bit of a personal question so feel free to ignore it. I was just wondering (assuming a 6 month visa and trip) what ballpark you were budgeting, as you seem to be further down the road to planning than me. Including flights, van purchase etc. We've been trying to work out whether it's likely to be next year or the year after when we've got the funds.
If you overstay your visa you can get blacklisted which means you may not be allowed to re-enter the country, which might not be ideal if your lass wants to see her parents.
Check their annual policy though for that length of trip.
BMC will extend for longer durations if needed at a nominal additional charge to std international travel insurance.

I know we've discussed this about a thousand times but are you flying into Vegas and when do you arrive?
Looks like you have a preference for long and mostly free?
