Answer a few quick questions
6-step fit recommendation wizardImportant notice
- This Fit Guide provides a starting-point suggestion based on typical builds. It is not an engineering analysis, a performance guarantee, or a promise of results.
- Actual cooling performance depends on ambient temperature/humidity, solar load, insulation quality, window coverage, air leakage, interior layout/volume, internal heat sources, and how often doors open.
- Power system needs vary with duty cycle, setpoint, install quality, airflow/ducting, battery capacity, and charging sources (alternator/shore/solar).
- Always verify system compatibility, required openings, dimensions, and installation constraints before purchasing.
