Will 13,500 BTU cool my camper?

It suits trailers up to roughly 25 to 30 feet in moderate heat. Larger rigs or full sun in the South often need 15,000 BTU or a second unit.

Does it run on a generator?

A 13,500 BTU roof-top draws a heavy startup surge. A 3,000-watt or larger generator with a soft-start kit is the safe bet.

No. It is a non-ducted unit that blows directly from the ceiling assembly, so it cools the main cabin rather than separate rooms.

It uses the standard 14 by 14 inch RV roof vent opening. The unit is about 31 by 30 inches overall and needs a new mounting gasket.

The rated maximum is 65 dB, which is noticeable in a small cabin. It is comparable to other non-inverter roof-tops, not to quiet inverter models.
