Solar Panels
Photovoltaic panels mounted on the camper roof (or carried as portable units) that charge the 12V battery bank from sunlight. Solar is the primary energy source for boondocking — 200-400W of rooftop solar paired with lithium batteries can keep a truck camper running indefinitely in sunny conditions. Panel wattage, charge controller type (MPPT vs PWM), roof space, and shading all affect real-world output. Factory-installed solar is increasingly standard on mid-range and premium truck campers.

Camping without any hookups — no shore power, no water, no sewer connections.
