Using your Boat as A caravan

[Bouba]

I've done it a few times on our last boat. Hauled it Spain and SoF.
We stayed in the boat as it is too big for any hotel, and you really want to keep to the motorways with a 28 foot on a trailer.

Strong word of advice though!
Overnight in VERY busy aires only with all the full facilities.
We around 6 years ago stayed in what was a busy overnight stop on toll road on way to SoF.

Pleasant July evening, lots of people around in the aire. Went to bed around midnight, at 4am knock on hull, 'Police' ....
full hour ordeal, with french drugs force police passports removed etc...

We get separated I am threatened with hand cuffs and arrest....
Short version, I smell a rat, row breaks out.
Police scarper.

Fake Uniform, Fake ID, Fake Police, and all inside the CCTV toll roads aire in France.

That is indeed very worrying. When I had a motor home I also had your idea for a busy, full facilities well lit aire for overnighting. Then we also got the knock, but this was the real bill and they warned us not to stay on the motorway as there were bad guys targeting motor homes and these two cops were all there were for the entire southern motorway. They said the gangs were coming up from Marseille. So I asked if it would be alright if we went further north. And he said then you get the gangs coming south from Lyon.
We took his advice and never again stayed the night on an aire
