Probably a similar number to those who write to holiday companies complaining that, "Nobody warned us there would be fish in the sea! The children were startled!"
We had a weekend away recently and having a chat to the warden and he said someone complained because he didn't warn them (it would be too windy the day after they arrived) for his tent.
MrT007, look under the label, have a feel the caps are there unless its not a standard lead acid battery.
A Varta Professional Leisure VRLA battery I have has no caps even under the label, the ABS casing is totally welded apart from the emergency vent port.
There is no way that's electrolyte will be being topped up without drilling into it.

40 watt solar panel will deliver max 3.333 amps.
This may take a long time to charge a 110Ah battery!
It may trickle charge it.
Distinct lack of sun here recently so perhaps expect less amps!
Yes, it would take a long time for a 40 watt panel to charge a FLAT battery, especially during the winter months, but the amp-hrs required to counteract any ongoing discharge would be a lot less.
Typically a caravan with tracker and alarm will put a drain on the battery of about 200 milliamps ( 0.200 amps ), and a 40 watt panel will be more than enough to replace this loss. It's always worth checking whether the panel is still working.
Just been to my van for first time since July - have had a bit of a rubbish time I'm afraid - and found the battery fully charged by the 40w standard equipment solar panel. Very pleased.
I do keep the van charged with EHU on campsites and the car charges it on tow, so it's maintaining a well-charged battery not charging up a depleted one that's been off-grid.
Never had any power problems with the motor mover.
