This would certainly be the easiest solution, but I can't help thinking (perhaps because I'm a little out of my element on some of this) that if they were "near dead" this would/should somehow show up, at least a little bit, on either the load test or the specific gravity (both were fine)?

Also, when using meter in ‘dc mode’, be certain to position the meter in the proper current direction - follow carefully the meter’s instructions …

I am using all 4 jacks simultaneously. Maybe a little overly simplistic way of thinking about it (and also maybe a little out of my element here) but it seems like the same amount of power/energy is needed to raise/lower the camper, so whether you break it into pieces (1 or 2 at a time) or do it all at the same time (all 4 jacks) shouldn't matter all that much. If I'm wrong, and doing 1 or 2 at a time would help solve my problem, please let me know.

The OP said the batteries are drained from removing the camper, which makes even less sense. Other than the initial lift off the truck bed, most of the time the motors aren't even loaded when running to remove it.

it's nearly impossible for the generator(s) to get them back up to an acceptable charge while camping
