My bus has the pictured inverter installed. Besides the brand name on the front, it has a tiny 'UL approved' label on the side with the number '94k1', that's all the identification I can find. That looks like it matches up with a Freedom 10 (1000 w). However the circuit breaker on the front is 25A, which matches with a Freedom 20 (2000 w). How would I better identify this? Is it intended for 12V or 24V?
The charging says it's working, but the inverted current seems to be very bad. I turned on one lamp with 120W of bulbs, it comes on at about half brightness and pulses. I can also hear the unit's fan pulsing with the bulbs.
Is there a replacement inverter you would recommend? I suspect I would be happy with 2000-3000 w, and 12V or 24V would be fine.

That looks to be the predecessor to the freedom 458. (Basically the same unit, just a name change) The freedom 458 would be the easiest drop in replacement, but it is a modified sine wave. (As is the one you currently have) if you want to spend a little more money and upgrade to a much better unit I would recommend the magnum MSH3012M hybrid inverter. Wonderful unit.
Edited to add: The freedom 458 has been out of production for several years but it was the most common inverter for a long time, so there are still many used and rebuilt units to be had. For anyone that goes to Quartzsite in the winter, I can tell you where to get them right off the shelf.

Thanks for the good word on Magnum. My batteries and inverter were wired to the generator and shore plug only. I removed my old inverter and generator and am planning to install a Magnum msh4024m wired to the engine alternator. I think that best fits my expected usage -- 110v while driving, mainly for a/c; plugged in most of the time when not driving.
