Hi Jay,
People like us who deal with a rear corner bed floorplan like you have shown, can relate to your concern. Our rig is not easy to set the bed. I am the official bed-setter and cheat to make it look nice at a glance. Changing the bedding is a real pain.
Everything has it's trade-offs. In our case, we needed something that fits in our garage.

Everything has it's trade-offs. Not just to fit in our garage, but we like to travel our national parks, monuments, forests and such. The shorter length makes it friendly for such places. So we deal with the hassle of the tight rear corner bed. At least everything else is perfect.
