I haven't made nearly as much progress on my Extreme Bus Makeover as I was hoping for. Everything has been removed from the bus except the fridge so it looks like a wide bowling alley right now.
The new floor is in and the underlayment has been installed for the vinyl composition tiles. I have a flooring guy coming this evening to install the tiles. The walls have also been covered with plywood front to back. Some of the plywood had to be replaced due to water leaks and some was never installed in the first place. (Water leaks are fixed.)
It gets easier now after the floor tile as I will mostly be putting things back in that are already cut and fitted.
sounds like your are really making progress! It should go faster now that the floor is in, and you have a much better idea what you're doing for each of the systems.
