Rob.
A few more tips come to mind- If you go in Dec/Jan try to park at lower altitude resorts ,it WILL be very cold at night that time of the year.Always try to park in a position that gets sun during the daytime,during Dec/Jan some valley areas and resorts get very little sun during the day so you never thaw out. A lift pass that covers several resort heights is ideal,you can move up the mountains to stay in later season or just go for the day.Many season passes give you several days in other ski areas if you want a change of scene.
If you want to stay most of the season in one area campsites usually do a seasonal pitch at a better price,still quite expensive with the £ exchange rate at the moment.
On the M/H front.A panel van conversion is too small and not well insulated enough for extended high altitude living,you will be inside a lot of the time in the early season,not much outdoor living.and the resort bars are expensive.If you want your girlfriend to remain so you need a little space.
Generators are tolerated on most aires but expensive to buy,not easy to store with petrol ect.Do not buy in haste.Some 2 stroke generators are cheap but put out a sine wave that is not compatable with modern electronic equipment.They are good for charging batteries with an old fashion heavy
transformer type charger like your Dad had or has.Do not plug into your M/H
you risk damaging the onboard equipment.
Try to ge a container to put overflow of toilet into if nowhere to dump is handy.A large opening is best.
Depending on your budget the best batteries for cold weather use are AGM construction (absorbed glass matt).These are very expensive but can last 10 years or more and are are unspillable.They are used as computer back up power (UPS).If you can find some decommisioned ones cheaply they are good.
Try to google somthing like Hawker Powersafe for specs.Dont spend too much its only camping!!!
You can try to hook up to a power source in the resort to charge batteries,girlfriend use hair dryer ect for the day .(Shop,cafe,if you are a customer it helps,chalet,garage,snow plough maint dept ect,a few pastis in the locals bar might help your cause).
LEARN THE LANGUAGE or at least the relevant stuff.Hook up ,gas,waste toilet dump ,drinking water ect. A phrase book is good and you can always point at the phrase.
Try to arrive fully stocked with wine,beer,food(plenty of variety of tins) ,gas ect
Its all expensive in resorts.
Its a great way to ski/board/climb/walk a variety of places and make new chums,we are doing our 4th trip this winter.
Take luxuries and be aware of you girlfriends
needs and wants if you want to live in harmoney.Seriously this is the most important tip of all!!!!
