I like the whole idea. Classic meets newer with a rubber boat twist. You have put a lot of thought and effort into making your dream work for you. Keep on keepin' on. What is your ingress with the outboard hanging on the receiver? I don't see any tie downs. Is the TC bolted to the ute body? If so, have you made accommodations for the flexing of the frame? Unfortunately, Ford, at least the slightly older ones than yours have a reputation for a lot of flex which will eventually pull your Avion apart if competely hard mounted. There are ways around this.
Post another update when you have the interior finished.
Good stuff.
