Ideas

• Use small shop-vac with 3d printed adapter to create floor-board dust pan that vacs up

IOT

• Cameras
• Apple TV?
• Bluetooth?
• Projector TV or real TV?

Kitchen

• Induction Countertop Cooker? (110V only)

Appliances / Major components

12V

• Water Pump (12V)
• Refrigerator (with Propane)
• Water Heater (with Propane)
• Furnace

110V

• Microwave
• Air Conditioner
• Refrigerator (w/o propane)
• Water Heater (w/o propane)
• Washer/Dryer
• Toilet (special)

Water System

Requirements

• Water pump from tank to faucets
• Water Heater?
• Hot Air Blower (Propane Furnances)
• Refrigerator?
• Lighting
• Safety / Warning Devices (smoke, CO2, Propane Detector, etc)
• Plastic Water Holding Tank (easier to maintain)
• Water Pressure Regulator when hooking up water externally maximum of 45-55lbs of pressure
• Water Filter
• Level sensors for all three tanks

Dump Tanks

• Black Dump Tanks store waste from toilet, which is vented
• Gray Dump Tanks are for everything else
• Waste valves for each tank will meet in a fitting for a common hose to drain both
• Black Waste Dump Tank has a fresh water clean-out valve

Gray Dump Tank

• Has p-traps
• Vents for each trap and one common roof vent for tank itself

Drain procedure

• Make sure tanks are pretty full when you drain
• Hook up everything from RV to dump site first
• Open the Gray Dump Valve and let a little flow out to make sure it's okay
• Drain Black Tank First
• Do not leave valve open, even if hooked up -- let them fill up

Electrical System

• 12V powers necessary items, AC powers "luxuries"

AC System

• RV's external power comes in 30 amp (three prong) and 50 amp (four prong varieties)
• many sites have 50amp, but some only have 30amp. Adapter available
• Apparently some campsites have bad polarity!
• Surge Guard on input?
• Transfer Switch?

12V System

• Battery bank of 12V power (deep cycle) (https://www.ohmmu.com/product-page/group-31-deep-cycle-advanced-lithium-12v)
• Solar Panels

Charging 12V System

This does not include the "starting" battery, which starts the engine.

• From external 110V
• From Solar
• From Engine Alternator

Requirements

• External 50 amp hookup
• Breaker box?

Propane

There should be a permanently mounted tank, they can be closed off and then driven through highway tunnels

• Higher-end may have a hot water system for heating the coach and hot water powered by a diesel system with a propane stove
• High end Class A Diesels are all powered 100% by electric
• Can only be filled to 80% capacity
• Permanent tank needs an always accessible shut-off valve
