How much fall over 6ft would be handy to know Clive ?
Oh Shayne, now you're asking, it depends where you park! I would suggest a part that's mainly just not quite even as opposed to sloping. If you're sleeping in the trailer, as I presume, it would be just a case of leveling the 4 corners to even out undulations to stop any movement.
On the approach nearer the house, it steepens, and there I suppose it could be 30cm over 2m or steeper.
Dont worry though, we'll sort all that on arrival. There's always a neighbour's land we could use if necessary.
We're also going to try to "borrow" another neighbor's house (Camelia). It's small and a bit cute (a traditional old build) but clean and tidy. She doesn't live there anymore, but she keeps the place up to scratch. It has beds and a lounge, a bathroom and a kitchen, water, gas and electricity, and a TV, so it would be more comfortable than camping, but it depends on what you'd prefer to do when you get there.
Again, no guarantees at this stage, but we're trying to broaden the options. We may even get one or two of our extension rooms finished. The thought of a 4th truck recently is good news, and really, there shouldn't be a problem as long as there's a mixture of campers and those who would prefer a roof over them.
We have a bathroom with a toilet, shower and washbasin, with hot and cold, but no bath unfortunately. Anyway, all we have will be at your disposal, so there's no need to panic.
We also have a semi-basement with a double bed settee and an en-suite toilet, shower and washbasin, so there are alternatives.
I always tease visitors by saying our house is like camping indoors, but it's not quite so bad
