Thanks for the numbers

The unit did a good job Keeping the rear section of the van cool. I did not cover the front windshield or side windows so I had thermal gain through the windows. Also I have zero insulation on the fiberglass high top.
At the 1 hour mark the battery’s were down to 77percent
At 2 hours 55percent
At 3 hours 34 percent
I had to stop at 3.5 hours and it was down to 30 percent .
My battery’s are 3 - group 29 lead acid marine battery’s
A small variable is I do have a 100watt flexible solar panel, however it’s a pretty crappy solar panel and in full sun it was only producing 20watts.
It did a great job dehumidifying the air and the drain rain almost constantly.

Using your numbers and guessing at your output voltage 12.25v, 12.0v, and 11.75v for 1st, 2nd and 3rd hours respectively I'm getting 790 watts average. This compares pretty well to the 12V RecPRo spec at 750 watts which looks identical to yours.
Considering rated at 750 Watts in an 8900 BTU AC which at 5000 BTU would be 750*5000/8900= 421 Watts (or nominally 60*5000/8900=34A.
With some insulation and a modest lithium/solar system, you could run quite a while during the heat of the day.
- This is the same unit being relabeled as RecPro at double the price (from amazon) but still much lower than most other options. The power is about 750 watts or 60 amps for 8900 BTU (12V)
- Rated input (12V:750W),(24V:850W)
- cooling capacity (12V:1800W(8875BTU)),(24V:2300W(13500BTU))
