You techie guys out there win hands down! I'm no carpenter or mechanic,
and I can't compete with any of your technical expertise,
but JUST IN CASE someone MAY be interested (

?), here are some pics
of the STORAGE MODS I've done on my 2011 RP 177.
JUST storage mods -- NOT inverters, risers, battery cut-off switches, etc., etc., etc. (although I wish I could) -- JUST storage.
THE GALLEY
This is the galley. I've put in a paper towel holder, cup rack, a wire shelf with baskets, and I made a stove top cover out of a tv tray (the idea is from another forum). I'm no carpenter, I used rubber doorknob bumpers and rubber chair tips to make the "legs" of the cover. The neat thing about it is that it doesn't slip or slide -- wish the legs weren't WHITE, though.
I also put some small woven fabric baskets above the microwave.
THE BATHROOM DOOR
The bathroom door has over-the-door shoe pocket storage. On TOP of that is an over-the-door towel rack with graduating rails that stick further and further out. To the left of the door is a clock (I used 3M velcro so it won't bounce off the wall), and a small pocket organizer.
THE SHOWER
That shower hose drove me crazy! I wanted it to lie flat against the wall when I wasn't using the shower, so I used adhesive-backed hooks to hold the hose. The mesh storage pocket and the corner shelf don't really look that "pretty" but I didn't want anything sticking out at me while I'm on the loo! (Maybe that is TMI!

)
THE DINETTE BENCH
I have two 10-gallon storage tubs with lids which go inside the dinette bench. Inside the bench are the 2 tubs, 2 collapsible crates, and an electric heater, Just this morning, I rolled up a couple of lightweight blankets into a plastic storage bag, and slipped them inside the bench, too. There was ample room for all!
UNDER THE BED BASKETS (2)
I have 2 rolling laundry baskets under the bed, and still have room for a small duffel bag, or some narrow storage bags -- you know -- the kind like blankets, quilts, or pillows come in.
OUTSIDE
An earlier forum suggested using PVC pipe to make extra sewer hose storage. I asked HOME DEPOT to cut a 10' piece of PVC in half. I bought the fittings for the end, glued them on with PVC glue, and screwed on end caps. I really need to attach it to the tongue with brackets but right now it's just held on with a couple of bungee cords. It isn't pretty but it works! I did have to take off the hose fittings and store them in a small plastic tub in the R-Pod basement, but I can live with that.
Thanks for letting me share my storage solutions. And thanks to everyone who gave me the ideas. Happy Podding Everyone!
