Boondocker converter setting
Maybe this is a silly question, but heck, i’ve asked my share, so... I have a Boondocker converter (the modified one with the adjustable voltage dial). Question is, what voltage do I set it at - th...

Set it to the bulk/absorption voltage, and check the water level in the battery at least once a month. Preferably, the charger could go to absorption for an hour or two when charging, then drop down to float voltage. But if your's can't do that, absorption voltage or a bit lower is correct.
But it depends on how often you use it, and how often you charge it. For daily use, set it to absorption voltage. If it sits charging for days/weeks between use, set it closer to float voltage. You can't really overcharge, instead you end up needing to add water more often.
Equalization is not the common case, so don't worry about it. And, it's not so necessary for an RV. A large part of the reason is to move the electrolyte around to eliminate stratification - and that happens naturally when bouncing down the road. The other reason is to balance the cells, and that only needs to be done infrequently, maybe spring and fall on an RV.
