Buy some bull clips, and use them to store the hotwater bottle, by hanging from the bottom. This let's them dry properly, and stops the sides sticking together, without putting undue strain on the rubber. Been using this method for 2 and half years on the same bottle, and it's still in good condition.

We’ve got a Berlingo Microcamper which is cozy. No draughts despite not adding extra insulation and stays surprisingly warm. Our diesel heater under our front passenger seat is our game changer! Padded (Aldi) slippers are great! We use Fleecy ‘teddy bear’ bedding on two quilts, one under us and one over us. Thin and thick - swappable depending on the temperature. We can wear fleece pyjamas when it gets really sub zero. It’ll be spring soon…

Keeping warm must be a priority in winter inside Walter , those boots and bed cover look just the job ........Take care

That's a great haircut bro much better bro 👍

Maybe grow your hair and wrap it round yourself to keep warm…!
