Now you say about the Rhino lining colour I remember you mentioning that before. Sorry, shoulda looked back through. Pictures look good. I like how you've curved the front corners. To be honest I don't like the shape of the front they are putting on. It's certainly going to be slick when it's done.
Cassette toilet's are meant to be good, and the 12 volt fridge will be great. Pointless setting up with a mains powered/three way fridge when you are going to be set up for the 12 volt, and there ain't no mains where you go anyway!
Oh, (zero stress, just sayin) the 'Outback' is Lara's domain (the land of Oz), we're just the little dot in the bottom right hand corner. Over here you drive too far in one direction you quickly end up in the Pacific.
