A MM sucks a heck of a lot of juice on pick up and then goes down to 25 amps ish on use. The built in charger is a trickle charger and will top up your house battery over a day or so. You could always plug in a reg battery charger and see how many amps it draws, that will give you a good guide to the current % of power held by your battery. If it sucks in 5 + amps, its low, 1 maybe 2 trickle it.

I may be wrong here but a good/new battery should be OK

It sounds to me like the van is drawing power. As JTQU says, a small amount of motor mover use won't drain much.

Some fridges draw battery power unless the control is set to off as do some chargers.

Try charging the battery then disconnect it and see if it holds charge. When you disconnect the first terminal, there should be no spark, assumong you've switched the charger off. A small spark means the van is drawing power somewhere.

The van charger will never fully charge your battery imo.
Your mover will be drawing a lot of power from the battery and it needs to be replaced by a good charge which I don't think your van charger can do.
I would recommend a good stand alone battery charger or a smart charger which will trickle charge and monitor battery charge state.
