Think very long and hard before coming to a decision.
Remember you will be using your motorhome/caravan as your permanent, not holiday, home in a single location, for months at a time.
First off is it well enough equipped/big enough to live in for an extended period?
What will you do with the inevitable wet outdoor clothing. Remember this is England so it does rain a fair bit at times
Will you have enough space for storing food and even more importantly, how will you get to the shops etc?
Do you have a second means of transport or will you need to use your MH? If so that will restrict any awning to a drive away type. Plus you will have the hassle of having to pack everything away before each shop run.
Tesco direct etc are fine for some things, but there is an awful lot they don’t
Is social life important to you?
If so who will you socialise with as you will be miles from friends and family and you will not be seen as a “fellow camper” rather as staff to be at their beck and call, by those staying on the site.
Do you really want to be cleaning the toilets EVERY day?
As well as emptying everyone else’s bins, cutting the grass, and all the other site “maintenance” (humping gas bottles etc)
So you need to look at what EXACTLY will be involved in the very clear light of day, remember it’s NOT another sort of holiday, it’s pretty much a 24/7 job as you will ALWAYS be on site so therefore can expect site visitors to have the expectation you are always available for them.,.
I am not trying to discourage you as some people clearly enjoy doing it, but trying to show the “other” side of job and raise a few issues that maybe you hadn’t thought of?
If you do decide to go ahead with it I wish you the very best of luck. I don’t THINK it would be for me though, I don’t suffer fools at all, let alone lightly, and sadly when it comes to MH’ers and caravaners, there seems to be a disproportionate number of them who are fools, or maybe incompetent or thoughtless is a better term for them.
