Go off grid indefinitely, Iʼve built a 20 foot long extreme off-road trailer that started life from a 86 Chevy pick up bed. Itʼs totally self-sufficient with 500 W of solar power going into a 450 amp battery bank. It is controlled by a charge controller and has a 1500 Watt go power inverter. It has a large queen size sleeper inside a small table full standup shower, toilet, 32 in TV wall mount with a powered antenna and a 700 watt microwave oven. The hot water for the shower is run off a on demand hot water heater. It also has a 5000 BTU AC unit a refrigerator with a freezer, A stainless steel grill and 2 burner stainless steel stove, one 8 x 8 Awnings and one 6 x 4 awning to keep you out of the rain. It carries 90 gallons of fresh water on board so you could boondock for a couple of weeks at a time and the toilet dumps into a 30 gallon black tank. This is a 1 of a kind trailer that is heavy duty built that will withstand the extremes of offloading and is totally solar powered and self-sufficient. Total gross Weight without water is 4200 pounds. That is a must see unit. I have a clean title for the rig. Call me at {contact info removed} for more details on (contact info removed)
