I think the idea is quite appealing but I wonder if the reality might be a bit disappointing.
For one thing, if you have invested quite a bit of money in a static caravan you might feel you should use it rather than have a holiday somewhere else. I think I might get a bit bored going to the same place all the time.
Then there are site and storage fees and, presumably, a certain amount of maintenance is needed. I have read of some unscrupulous site owners putting up fees quite substantially.
I can see the attraction of a tourer if you are a confident enough driver to tow a caravan.
