I really wanted this to work! I even started planning how I would permanently vent it outside and ordered some of the parts. BUT, the initial test results are completely and utterly pitiful. I guess you get what you pay for! My expectation management bar was set very low and this unit didn't even see the bar, let alone try to get near it.
My insulated truck cap is only 100 CUFT. So I assumed (assumptions kill) that this unit would be a rock star!! Yet after a 4 hour test, I barely got a 4 degree drop in temps. I ran it off my garage power, not my batteries just to see how it works. I used 2 temp sensors, one outside and one inside. I vented the exhaust and intake outside and sealed the gaps, relatively speaking ( love my ol 1980's era 30* army bag!! (which I absolutely love btw) For the record, I was not trying to be scientific nor exacting in any measurements. Just seeing if it works. The temp of the exhaust was up to 120* F. The intake was close to the 95-97* ambient temp. The first 2 hours I ran it at 72*F and it barely changed the inside temp. I lowered it to 60*F which is the max and I finally got movement but after 2 hours, only 4* drop.
Time to reset and look at a refund and get an RV mini split. I have always kept my eye on the unit in the link below but didn't want to spend the $$$$. Depending on how it feels on my next trip (July), if it is sweltering at night, I might have to bite the bullet. I wrote the company asking for power usage as the web site only lists the amps. We will see based on their reply if it is viable!
