A/C
Choose verified cooling capacity at relevant ambient temperature, DC voltage range, current, noise, condenser configuration, service network, refrigerant, control/low-voltage behavior and warranty - not price alone.
Fans and controls
Choose continuous-duty airflow with safe guards, adjustable speed, modest current, durable mounts andtolerable noise. Three weakly placed fans are not automatically better than one well-ducted path.
Envelope products
Covers must fit, stay outside, resist wind/UV and not scratch. Reflective materials need the correctair-gap/application. Awning size, mounting and wind limits must match the van.

System rule
Do not judge a cooling upgrade at the vent. Judge it by the hottest occupied zone, humidity, energy usedand whether the system can recover that energy safely.
CHAPTER CHECK
• I can explain which heat path this step addresses.• I measured its effect at front, middle and rear - not only by touch.• I added its power, failure mode, maintenance and safety action to the system plan.
