I'm guessing they are, based on films and series filmed out there. I'm also assuming (given the huge size of your country) that it is easy to park somewhere for the night and get some sleep.
They're called minniebilbos actually.
They’re not just big, they’re huge, probably double the size of ones over here.
It wasn't an illicit drugs lab which got confused over hydrogen peroxide, was it?
I've seen an RV that contained a Smart car like a Star Trek shuttlecraft.
In ThatCanada, I quite often see them with a Toyota Rav hitched up on the back, the way you would a Bicycle in the UK. They are very large, it is a huge industry and yes it is pretty easy to find somewhere to park up. Much larger countries you see.
Having an RV after retirement is an aspiration to some. There are some luxury convertible RVs in the market and there is a covid inspired fad of RV lifestyle among remote-worker youth, if I were to trust newspaper columns.
RVs wouldn't fit on those narrow roads in the English countryside.
I saw one in Australia which was so big that it had a built in garage for the little runabout car.
Locally, in a normal year, a lost of people move into their RV and rent out their house for the summer.
And there was the RV, a bus conversion, that had a full-size marble tub installed.
Rock groups are noted for having over-the-top bus conversions.
The greatest conversion of all time?
