Some of the systems that you just posted show a draw of amperage with the batts 'connected'. You have 'full power' to the fuse box and a small drain/draw going to some of the systems. This drain is not enough to cause your problem (imo).
Pulling the 'batt disconnect' and measuring between the camper ground cable and the neg bat post does not test all the way to the fuse box.
There is a break (batt disconnect) in the line that should not be there.
The batt disconnect is (I think on yours) is the Pos side of the batt. We need to stay on the Neg side to see amperage coming from
the pos side.
We are looking for a power drain. you must have power to find the drain. Keep batt disconnect 'on'. A 'hot' wire is 'grounding' (on) to a system/frame/ etc. Is this 'before' the fuse box or after the fuse box? you have proven the amperage drain on some systems after
the fuse box. Now remove all of the fuses in the fuse box. you still have full voltage to the fuse box from the pos cable (if the disconnect was 'off' you would not, so leave 'on'). To test any parasite or 'shorts'/grounding, we now pull the neg cable post off the batt and check for amperage between the cable and post.
See what we have after you do that.
If you have amperage going through the meter at the neg post and cable with no fuses in the fuses box (disconnect on), your problem is somewhere from the Pos cable to the fuse box.
