No experience with the Okanagan at all but my neighbor in Cascade Idaho had a Bigfoot as did one of my friends.They are top shelf campers..I have owned a lot of truck campers over the years and my favorite was and is the Lance,that I have owned.
I am already looking for the next truck camper for my truck and it is going to be either the Bigfoot or the Northern Lite.Weight is a factor as well as the likely hood of leaks or potential leaks.Living in the mountains of Idaho I see alot of gravel/washboardy roads as well as the twisting and tweaking that goes with semi off road.It is next to impossible to keep a standard build truck camper such as the Lance/Arctic Fox etc from cracking a seam or a bead and I am anal about leaks.
Don't get me wrong,there are alot of great truck campers out there and the Lance has treated me very well,all things considered..Trying to find a used Bigfoot even close to my area is almost null compared to all of the others and my area was and is limited to 200 miles which includes Spokane/Boise and Missoula.
In your area you will have a better chance of finding either so be ready with cash in hand as Bigfoots in excellant shape do not last long on the market from what I have seen, looking.
Good luck in finding what your after.
