I really haven't messed with specific types of wood before. It has been an education. I have looked into Birch Ply, Baltic Birch (I started out thinking this must be from the Baltic region), Finnish Birch and Russian Birch. Now there is bendy Birch!. I hadn't seen it before but it sure looks interesting. If I can find it local I may give it a try. If not I was going to try a hot water bend of 1/8 inch Birch ply. I have never tried that procedure before so I thought it might be interesting. I do get in more trouble that way. Without the floor in I think I can get a good clamp on the side rails and good access to mess with it. If it doesn't work for me I'll need some material to re skin most of the cabinets anyway.
There is something cute about the thing and I don't even normally use that term on something with wheels. Here is another picture showing the thing end to end, and Clyde again. That odd mix of a dog sure likes spending time with me when working outside. I also recently noticed he seems to be posing when I get the camera. I don't really expect he knows what the camera is but I don't place him in the shot.
As far as the layout these cabinets are just placed in position. There is another seat across the back connecting the two bench seats. You can see in the different shades on the side of the tall cabinet where the other cabinets and counter top across the front fit up to it. The top of the tall cabinet is about 5 foot off the deck. That's actually tall enough for a standie for my wife. There is another 12-14 inch for the popup section on the roof.

Cutting a relief Kerf up to 2/3 of the way through the plywood and gentle pressure is time consuming, but less aggrievating in the long run. 
I was missin for a few days. You shouldn't need water to bend most 1/8" 
Just be gentle. You could use a strap to nudge it over a period of time if needed. 
use bendy for the thicker stuff.
