My fitout was perfect when it was finished, now I'm carrying lots of gear on the bed as well. Oh well, I guess that happens with any layout as you just accumulate more stuff.
The bed is a series of high grade marine squabs, they will drain through and not get mouldy plus can be thoroughly washed with fresh water. Together the squabs create the size of a queen size bed so all the bed sheets etc... are easy to get and fit. Also got Velcro fly screens for the doors for the fly/insect heavy days and nights. The roof and sides are all heavily insulated and painted black inside. Not only helps with the temp, it really keeps the noise down at night and it's dark for long sleep ins. Anecdotally discovered flys don't really like going into darker spaces!
On longer trips I use thee roof box for all my sails, masts booms and wet gear. Helps keep the van clean and dry for sleeping. Any internal rack system would impede on my fly-less, day lounging experiences watching whales, reading and drinking breakfast beers ;-)
