Best Of

@hammerstone, We didn't like the hassle of the queen bed setup and the difficult access to the toilet in the middle of the night.  Once we decided the "2 twins" was the configuration that worked best for us I purchased a queen topper, cut it to be slightly wider than the benches on the sides and sewed the topper cover back.  We use these on top of the existing bench cushions.  Next I built new side bench wood covers for the cabinet areas over the wheels.  I inset a 3/4" peg in the under side of the covers so when I slid them out at night they would stop at the appropriate width of the topper.  I didn't try changing the cushion size as I didn't want to get into making new cushions, I just pulled the cushion out with the slide and dropped a 3" diameter pool noodle in the gap at the side of the camper, it works fine to fill the gap with the topper laying over it.  Next I bought a  Lagun table mount and made a custom table top.  In the "awake" position the table opened up for fine dining, puzzle working or laptop table.  In the "sleep" position I fold the wings up on the table and spin the mount around to provide a bedside configuration for whatever you want close at hand.   the way we use our T@b we almost never pull the bench back vertical so when we get up in the morning we just roll the topper up toward the back and we're ready for the day.
The twin bed setup makes it easy for the early riser (me) to get up with our GSD and go outside without bothering the better half.  
The pics below mostly show the table but if you need any more detail I can easily provide more photos and descriptions.
(due  to some technical snafu I was not able to get my pic selection to upload to the document)  I'll work on that and post the pic later.

I’ve seen a picture of a Valterra sewer hose tube attached to the back handles of a 320S but for the life of me cannot find it. I tried my own application this morning with zip ties, but couldn’t keep the tube from rotating on the handles. Would someone who has done this mod post some pics of how you attached it? A not so handy old guy would appreciate it!
