Leaving PVC for a week while ski-touring

[RobbieH]

We have a 2021 Adria Twin which we'll use for some ski-touring this year, a couple of questions ... When leaving the van for a week to go touring around the huts is it better to drain down all the water, open taps etc. Or is it better/safe to heat the van at a low temp ( two 11 kg bottles) and leave the water systems full. And does anyone know how much current the grey water tank heater draws? Will I come back to a completely flat leisure battery if I leave that heater on?

The tank heater will flatten the batteries in a week.

If it was me, I would drain down and not risk it. You only have to have a small issue suck as forgetting to turn the gas on, power cut, fuse blowing and it could be very expensive.

As an aside check if your insurer allows you to leave it unattended for that period of time away from home.
