We have a 2016 Expanda caravan. Due to problems with our previous tow vehicle we have not used the caravan much in the last 18 months. However, we have just bought a Patrol and last week had a towbar and caravan electrics installed so today I connected it to make sure everything worked. One extra thing I had fitted was an Anderson plug to at least better power the fridge whilst driving. Today I then disconnected the fat accessory cables from the caravan 12 pin plug and wired them into an Anderson plug and connected it all. Finally now the fridge runs from the car which is great but how can I tell if the car is charging the batteries? Is this meant to show on the drifter monitor because it just shows discharging? Or is it just like charging from solar which doesn’t show on the drifter? We’re heading off on a weeks holiday before Easter and I wanted to make sure all was well with the van.
