Parasitic load discharging a chassis battery over a period of time is a known problem for some camper vans, it' quite a common reported issue with some ex Ambulances
Various products are on the market such as the relatively expensive Ablemail AMT12-2, the quirky Sterling BM12123 or the Votronic battery Master.
A similar device to the Votronic unit using just a fuse, diode and light bulb can be made for pennies.
This solution isn't by any means perfect and could occasionally pop the fuse due to the very brief inrush current across the bulb if the chassis battery is heavily discharged when first connected up, but it does work and is ideal for use when a vehicle is left standing for a few weeks between trips.
Diode used here is a P600B
