Hi Thomas
If you're talking about Otto Mobiles, I don't think they would be able to help you out much unless you had a very new
Bigfoot.
Have you tried Murphy's RV at all? They are located north of you near Josephburg. They used to be south near Leduc and I visited them at that location. They had a LOT of older, hard to find parts. I'm hoping to make a trip there yet this
fall.
Their contact info from the Yellow Pages:
Murphy's RV Parts & Service
21338 Twp 550, Josephberg, AB T8L 4B8
Telephone : 780-992-1830
What parts specifically are you looking for? People here have sourced a lot of different items and if they know what you are looking for they might be able to point you in the right direction.
