I have read that alarms and trackers drain the leisure batteries even if they are not switched on. Is this correct?
I am wondering how long our batteries will last if the van has the alarm and tracker on. We have 2x100 amp leisure batteries and a 100w solar panel and have been fine off grid for up to a week with a compressor fridge and the tracker on but that was when the days were longer and the sun(mostly)shone!

Can anyone recommend a wheel clamp or similar mechanical security device?
