If you dig enough you will find that on the better battery sites.
I grew up when flooded wet cells were all there were.
Can you provide a link to one of these sites (not your opinion but actual site link)?
Every one I can find says to fill to the bottom of the fill tube but keep the slots on the side of the tube clear.
Of course, the big issue is keeping the plates under water but it's hard to tell how deep they are if you just eyeball it. If you just barely cover them, as you are bouncing down the road, the top of the plates will get exposed and degrade. Using the tubes gives you a built in gauge to determine when to stop.
Honestly, if the rig is in storage and not in use, disconnect the battery once fully charged. You might check on it every 2-3 months but if fully disconnected it should hold a charge. If you use an existing battery switch, make sure it really disconnects everything.
