Thanks, Tango. Glad you had a good, albeit hot, summer – I think we all did this year, didn’t we?
Apart from the usual service items (you’ve already indicated oils, fluids and tyres) the BIG thing to keep an eye on is the engine timing belt. If this breaks it can destroy an engine. Also it is NOT just dependent upon mileage… it is also time sensitive too. It’s a combination of both, mileage or date, whichever is soonest, so I’d recommend you look at that first. It’s always a good idea at this time of year to go round the various door seals and wiping them with a thin coating of silicon grease. This stops them freezing and sticking, preventing the necessity to purchase an (expensive!) replacement. I highly recommend products like Rain-X for the windscreen, which really proves their worth in winter driving conditions.
There’s nothing specific mechanically on the Exsis, over and above any other similar commercial vehicle, except maybe the windscreen wipers. Ensure that the joints are lubricated, not ‘binding’ and are not coming loose. These were a Hymer-workaround for a problem where the windscreens weren’t being legally wiped.
As far as keeping the pipework ice-free when conducting wintersports, the Exsis was actually made for this sort of activity. All the water, fresh-, waste-tanks and pipes are inboard, which means that provided you pay attention to ‘normal levels of warmth’ within the Exsis, then nothing should freeze.
Good luck.
