OMW from UK

Hey friends

It's the first time I've owned a van since The Great British Oopsie and I'm booked on a ferry Newhaven>Dieppe for 2 weeks leaving next week. What do I need and need to know?

SIM cards - are e-sims the way or can I buy PAYG sim card in Dieppe that are good value?

How are Aires working these days? I have a Toyota Noah which I'm putting a bed and slide out kitchen into. I'm just using USB battery packs etc - my electrical needs are pretty slim for this trip but toilets and showers would be good, I have a shewee and a leatherman and a gas stove and can get a USB tap and washbowl or something. I feel the cold like a newborn and don't have a night heater so maybe I need to be below a certain altitude?

It has a car type tailgate - I'd like to take my e-bike (25kg 20" wheel lwb town bike) but I'm not sure how to attach it - it's wider than the van. I can fit it inside - but I might not be able to after I've fitted bed!

I've not planned a route beyond some family engagements that will take up the first 5-6 days that will take me as far south as Toulouse. I'm mainly down for views, throwing a yoga mat out thermal spas. Also feminist art, cake and a little wine. I had my car written off by hail driving Rue de Napoleon to the spas in the Alps last time I was travellin....I was aiming for Lake Annecy and still really want to go - but maybe not this trip? Prob planning to stay in France and no more than 4 hours a day driving for the latter half of things.

Thanks for your thoughts
