Help - jacks are draining my batteries
My 2020 camper came with HappiJacs which consume a ton of power from my 2 deep cycle batteries. Once the batteries are drawn down after removing the rig (3000 lb dry weight) from my truck, it's nearly...

5 pages later, all the hypotheses about the finer points of batteries are fun to read but OP,
In this order.
Dueling 2k gennys is overkill for anything but running the AC. Will easily power a normal size converter on a single 2k. Not the issue.
You just need to figure out what’s not working right. (And make sure you’re not unnecessarily draining the batteries like by running fridge on DC)
Easy simple way.
Charge up batteries with a battery charger. Surely you have one. If not, get one. Assuming it’s just got 2 run of the mill 12v batteries.
Then run the camper up and down through a basically full cycle. Not hooked to shore power.
If it does that ok then the batteries aren’t bad. If it does it twice, batteries are just fine.
If it doesn’t then the batteries are junk.
If you’re actually charging the batteries appropriately with the converter and don’t get the same result the converter isn’t doing as good as it should. But you gotta know you’re at least roughly charging long enough on shore power (converter).
And until you do that and give a clue as to what converter you have and the other questions you haven’t answered, this is the best approach to figure it out yourself.
