Fandj,
Very nice work, also noticed that you did a significant upgrade in the draw locks you used.
We spend 4 plus months living in ours so am also always in search for improved storage.
I discovered recently that there is a "significant" amount of unused space between the outside wall and the outboard partition of the bed on the drivers side, where you made your changes. However in the area is the gasoline fill inlet, shore power and lots of wiring. I made protective partitions so as not to jeopardize or damage anything already there, basically small boxes, then cut an access hole in the top of the fixed outboard bed board, like the one on top of the passenger bed. It's not a lot of extra space but it will be useful for infrequently used items.
Your earlier posting about the shelves in the bedroom, we've debated doing that, but elected to make cloth pouches, my wife did, they are just big enough to hold our IPads, phone etc. The back of the pouches is long enough to go under the mattress where it is velcroed down. On our trips this summer they worked in keeping things off the floor at night.
I noticed someone recently posted that they ordered their new PC with the old style couch with the two draws underneath. We really miss those drawers that we had in our 2350 and if to do it over again would ask for that change, personally I think the couch was more comfortable also.
Again lovely work
Bob
