Wiring for Power Tongue Jack
I'll be installing a power tongue jack. I do a fair amount of dry camping, which means I am frugal about my use of battery power. I selected a power tongue jack that uses less energy due to a ball-bea...

I think you're overthinking the power usage of the jack. It would use a fair bit of current, but how long do you run the jack for in a weekend? 30A (which I'm guessing may be larger than the actual current, though I don't know) for two minutes (a good bit longer than it takes to get the jack adjusted, I would think) works out to a grand total of one amp-hour of charge consumed.
It's the same basic reason why the water pump's power use is pretty low on the list of concerns: the run time is comparatively small, so the total energy usage is quite modest even though a nontrivial amount of power is required.
