Always been less than satisfied with the main cabin mattress. Too narrow / too short (I'm 6'3", 240#), was layered with loose foam sheets from previous owner, also had that 'boat smell'. Plan is to shop for a custom mattress at HMC showroom near Cleveland OH while visiting the new grand-baby. I took the old plywood platform sections home and fabricated new pieces resulting in 6" wider at the shoulders and 4" wider at the foot and 4" longer overall. All that is left is to fabricate and install Aluminum molding / lip to hold the new mattress in place. Made a template of the new footprint to take to the mattress folks.

One issue we always had even before the modification was the hanging locker doors ran into the bed before the door was open all the way. Took the doors home / split them vertically, installed piano hinges after some teak edge banding on the raw edge. Now we have bi-fold doors that clear the bed and give better access to the hanging locker. I'll post picture when I have a chance - turned out pretty good.
