I'm looking to purchase a low profile van rooftop air conditioner. It should be efficient, lightweight, and designed for various weather conditions. I need something that can provide reliable cooling while not adding too much height to the vehicle. Could you provide me with details on your available models? I'd like to know about the specifications, including energy consumption, noise levels, installation requirements, and pricing. Please also share any warranty information and lead time for delivery. Thanks!
