Thanks Matt,
I received the plans today.
I thought I better reserve the topic name just in case someone else wanted to use it
I won't be starting it for a while as I have to finish other things first, such as the S&G kitchen for our camper trailer.
My wife also would like the back extension completed. I don't think she likes walking across the floor joist on a couple of Aluminium planks

plus it will look better with drywall/ceiling fitted and painted.
That will give me time to get the Paulownia for stripping for the Sabalo SS&G.
Cheers Mike
