At this point LED is the only way to go. I have a couple options on the beds. One is a set of tumble and fold benches over the wheel wells, a Murphy bed, a bed-mounted on a lift and making a removable frame that attaches with e-trac. A good portion is going to depend on how the wife wants to floorplan laid out.
I will likely make the second bed something that can be removed quickly and not permanently attached. We will be empty nesters in a few years.
I have been looking at a lot of conversion builds online. There are definitely talented and creative people out there.
