Autonomy stack

Disappear for months. Still live like you won.

Weekend campers play dress-up. Goliath is the real thing — purpose-built so two people can go dark for months without asking anyone for power, water, or permission.

The equation nobody else is running

13 kWh lithium + 1200 W solar + 100 gal fresh + 100 gal diesel + Honda EU2000 = months of autonomous living for a couple who refuses to settle.

Why Goliath

Specs that flex. Systems that deliver.

Every number below is a reason someone else will ask what you drive.

⚡

13 kWh lithium + 1200 W solar

“My campsite has better power than your house.”

Renogy-monitored house bank (~919 Ah class), 32 A alternator charge, Blue Sea marine-grade distribution. Continuous off-grid living — not a night-light battery.

⛽

100 gal diesel · 100 gal fresh

“I don’t schedule adventures around gas stations.”

Triple-digit fuel and water. Grey 14 / black 5. Engine heat-exchanger water heater so hot showers don’t kill your battery ego.

🏔

2020 F-550 · 6.7 Power Stroke · Allison 10-spd

“The chassis is the flex. The camper is the trophy.”

Super Duty bones, Buckstop armor, PIAA lighting, front-basket backup gen. Built to look expensive in every mirror you pass.

↕️

Kelderman Airride · 8″ of flex

“Level it. Camp anywhere.”

Custom made and installed by Kelderman in Iowa — eight inches of travel so you can dial it flat and camp anywhere without hunting for the perfect pad.

🔗

16,000 lb Warn winch

“Get unstuck. Or get someone else unstuck.”

Front-mounted Warn winch rated at 16,000 pounds — recovery when the trail gets serious.

🌙

Front FLIR camera

“Night doesn’t end the trip.”

Thermal FLIR up front so you can see in the dark — wildlife, trail edges, whatever’s ahead when headlights aren’t enough.

🚿

Hot water that actually lasts

“Real showers. Real pressure.”

6-gallon heater — electric and engine heat-exchanger. Once it’s up to temp, nearly 45 minutes of hot water through legit shower heads with strong pressure.

☀️

Rooftop deck · fold-up solar railings

“More deck when you want it.”

Full rooftop deck — and two of the solar panels fold up to become railings, opening more floor area up top.

🛏

Purpose-built for two · months off-grid

“We don’t share the wilderness with amateurs.”

Sleeps 2. No slides. Rooftop deck + awning. Dark premium cabinetry, loft + dinette — a private expedition suite, not a party bus.

🔧

CO2 Power Tank · Blue Sea · Renogy

“If it’s not expedition-grade, it’s not on the truck.”

Air up anywhere. Marine electrical. Propane galley. 30 A shore when you want soft living — Honda EU2000 when you want total independence.

🛏️

Cab-over reading lights + fans

“Your side. Your airflow.”

Cab-over bunk with individual reading lights and fans — each person controls their own comfort.
