Yep. That'll do the job for sure. Looking forward to some finished product pics. Hope it all goes well. Thanks for the pics.

I was only talking to a truck driver in a rest stop today and he showed me the 'truck'. no windows so looked just like a truck parked in a rest stop. Until he opened the side door that had a screen security door inside as well, out came fold down steps that the door was hiding, he did have a rail type step under the door as well and shut the front gate! Just like a caravan inside. Light comes through 3 big roof hatches, one being a four season for air that you can't see any of them from outside. The driver cab has covers that go all round to make it look like someone is asleep in the cab.

Your photo's look a smaller scale version but with windows.
