Agreed on height, more is better but the other 2 boards require fixed backscenes as they curve. The maximum height for my crate is 46inches so space for all three is going to be tight. This is the maximum size that will fit my van! I have worked out that I can get 2 of these crates in there allowing me room for 6-8 boards if needed, whilst still leving space for the ot her bits and pieces to run the layout. I am amazed Pete that you have built so beautifully without workshop space!
I think that 18" is the biggest I can get on the other 2 boards so I am going to try this next. Tomorrow I might try doing some more work on it. I'm going to work on the SDR on Tuesday as a volunteer so I'll blog that too.
