How long off-grid?

Boondocking endurance for this floorplan — modeled from its real 2.5 kWh battery, 300 W solar, and 39 gal fresh / 37 gal gray / 35 gal black tanks.

1.2 nights Battery-limited

House battery runs down first under these assumptions.

How this is calculated

Power: usable battery = nameplate kWh × 0.8 (blended depth-of-discharge). Daily load presets — light ≈ 1,500, moderate ≈ 2,800, heavy ≈ 5,000 Wh/day — from published boondocking power budgets, excluding air conditioning (no trailer battery runs rooftop AC for long). Solar harvest = panel watts × peak-sun-hours (summer 5.5, spring/fall 4.0, winter 2.5) × 0.7 system derate. Water: per-person daily use (light 3 / moderate 5 / heavy 8 gal fresh; gray ≈ 80% of fresh; black from toilet use) against the real tank sizes. Endurance is whichever runs out first. Estimates for planning — your real usage varies.
