Here's the finished product. Pretty basic, but it works for my needs. I relocated Iceco and will need to build a slide, or breakdown and cough up $240 for Iceco's (Aaarrggh). I will likely lower the whole platform when the new power box is done. Those are the Adventure Van Co. Shades shown rolled up with their magnetic ties.
Hest (sadly 25" not the new 30") fits nicely, a bit tight vertically but good for me. Think bunk bed.
Rear view showing Bed platform foot support storage on top of Iceco. 3 people could sleep inside --. I may actually sleep under the platform. We'll see.
Close up of bed foot storage on top of Iceco and rear support brackets on 15/23" Roseburg AC ply with iron-on edge banding. Grey stain to resemble computer grey interior, a bit yellowed by Varathane spar urethane.
Closer view of 28" bed platform foot section flipped over for storage. The M6 fasteners that attach it to the extruded aluminum double as storage points. Yes, 15/32" ply warps but lies flat when fastened down (as you can see fromthe main platform (48" x 61"). Lots of width. Bed is 76" long.
.
Foot piece storage from the passenger slider. Foot piece M8 knobs of far right. Front (2) Skorvas not shown.
Detail of the rear overhang support brackets. 1/2" hex into the Skorvas and 3/8" into the bed platform.
Close up of the extruded aluminum in its storage place on top of Iceco. I'll likely use 3M Command strips to hold it down, although it hasn't moved yet. The bottom of the extruded piece has corner brackets as feet that hold the piece in place on top of Iceco.
And here's my first cut at a 16" x 36" 2020 extruded aluminum power box that will allow me to drop the bed platform while still accommodating black and yellow big box store storage boxes.
Blue rectangular box is 2000 W Renogy PSW inverter, beige boxes immediately below it are 2 100 Ah self-heating Renogy LiFePO4 batteries, green is 50 amp Renogy DC-DC charger & solar MPPT. The other parts are Blue Sea Systems fuse boxes, bus bars, a shunt for the battery monitor, and grey is the Mean Well DC power supply to simulate solar (poor guy's inverter/charger set up) from shore power. I have a solar disconnect so I don't need to worry about the panels when I am plugged in to shore power.
The batteries sit sideways, terminals to the right. The extrusion the inverter sits on will be moved inboard as needed and a second extrusion will be added to support the relatively heavy inverter. I may be able to cut down to about 14".
