Steve, I'm going to scale all the pieces of the old floor and see what the "net loss" is. The trunk section weighed 30+ pounds all by itself!
Thanks Don. The old floor had been patched up and otherwise brutalized, seemed like the only way to get any structure and have the floor looking decent when it's done. The flat section behind the seat platform will be carpeted so Pepper has a nice place to ride too! Hard for him to dig his claws into the aluminum floor so I'll make the weight concession so my dog can ride!!!!!
