I do have a compartment between the tall one in the corner and the wheel well, but it fits completely under the lower level of the bench compartment.
I thought the same thing about the bed 'legs', but I believe they could be attached with hinges and
folding table leaf supports, so they could be moved out of the way when the top is opened, or even folded flat against the bottom of the bed platform before it's closed for storage.
Yes, my side window is low, and so is the cabinet above it with it's thick padding on the bottom. I'm 6'1" and when I sit on the bench with it's existing ambulance pad, my head just does hit the pad above, so it's got to go for sure. I may replace that pad with a much smaller and thinner pad on just the outer edge. Since mine is a trailer no one will be in it when it's moving, so big head banger pads aren't really needed.
As far as the window opening, I thought about using pads that were shaped like the
old style truck bench seats that don't, have removable headrest. The area in between the molded in 'head rest' would be the area under the window. This would work fine until it came time to convert it into the bed, and there would be gaps along that edge.
If there was a perfect solution, I would have it done already, but this is not a high priority right now and I've got a ways to go before I get to this point.
