I'm rethinking and removing the idea of a "supply depot" and leaning toward a "repair depot" 
this will add

and the Sherman can then have the engine deck open and the above White scout car can have it's hood (bonet) open.

Thoughts?

How many vehicles will you have in the dio?

This sounds very interesting.

@harold-adams
2 White scout cars, Greyhound, M26 tractor and Sherman....   maybe a cargo truck but maybe not

What company made the other Scout car? And which was the easier build? Just curious.

@harold-adams
It's Hobby Boss early version (picture above) and this one below is Hobby Boss later version and it was nowhere near as simple and error free like the Tamiya White scout car.

 But I'm hoping it won't be so fucking bad this time around now knowing what to look for. The reason I'm getting this is because I can build it as being repaired as it has a engine and the bonet can be opened.

@ron yeah that sounds like a plan you'll beable to show off your Sherman interior 👍 👍        

Now I'm debating on the line up, so the two that for sure will be in this is the Sherman and White scout car. 
Thinking about removing the Tamiya White scout car and maybe the greyhound and going with either or both

 or 

 or both on the diorama

 feel free to post your thoughts

Hows the construction on the RFM Sherman?

For the figures, what do you have in mind?

Also I was on the M& Models website and they had something that would be a nice addition to your diorama; Here's a pic.

I have stopped on the tank while I build the White scout car, and working on it's stowage as well. But will have to get the rails around the inside before I can fully see what will be used. Also I have that and built one of them already and also got two more kits for this diorama.

Basic layout to see how this will look
