Key Cross-References
- Power ↔ Insulation — envelope halves AC load before AC runs (Air Conditioning + Insulation)
- Weight ↔ Build-Out — ~350–550 lb added; must verify payload first (Weight & Capacity)
- Solar ↔ Generator — gen-carried regime drops array to ~600–800W (Solar Quotes + Power Supply)
- Frame ↔ AC — 80/20 window frames double as AC panel + insulated inserts (Air Conditioning + Insulation)
