Made a portable power station/ tray. Small Life battery, Solar panel, Charge controller/discharge protection, Cig lighter input charge 12/24v. Small AC Inverter. Great place to put sunglasses, charge phone, headlamp, holds/charges my handheld that does 2m FM Marine and AM aviation receive. My charge controller/led lights make some RF noise that is annoying on the handheld but if I place it 4 feet away its useable. Red/White reading light. Cig Lighter power-out runs a fan all night.
Built a kitchenet that goes in the copilot position. Holds my cooler, small sink for throwing in greasy utensils, wet rag. Shelves for water jugs, cans of soup, snacks. Place for my cookstove. I need to paint the sink top with a good heavy coat of latex, flashing the backspash stove area. The whole assy holds down with a seatbelt. My buddy suggested a net over it for turbulence. So far I have been able to warm up soup at 17.5.

Modified a magnetic screen door to cover the Utility door and a window for bug free ventilation.

Went to ArkanSTOL for a few days and my system worked out nicely.
