Yes, we lived in one for 18m whilst the house was uninhabitable.
We got a 3 bed so that the (2) kids could have their own bedrooms (take out the second bed in the twin rooms to give them some more space for toys etc.
If you even vaguely think that you will be going through the winter in it, get one with double glazing and central heating. Get some oil filled radiators for boosting the heating when you need it. Heat is lost through the floor so if you can block it off with straw bales to stop the wind howling through, this will help.
Ruthlessly declutter what you take into the static, including cooking stuff. You only need 4 plates as you have to wash up after every meal because there is no space to leave things out - you get the idea.
Likewise dial down your haute cuisine cooking recipes and get good at what can be done on a hob - the kids still refuse to eat filled pasta and we've been in the house now for 3 years. I didn't do a roast or bake a cake the entire time we were in the static as the oven wasn't up to it (I would normally do both once a week - cakes poss more!). Your fridge will be (relatively) tiny, I had to change shopping habits to 2/3 times a week (rather than once) just because I didn't have enough cupboard space to store a normal shop.
Try to have your washing machine and tumble dryer (in winter, you cannot dry things in the static very well without damp getting everywhere) plumbed in in the house if you can - sometimes I would wander round it in winter with a torch to try to find them, as the builders had moved them, but it kept them out of the static and under shelter.
Always have a spare gas bottle for when you run out at 9pm on a Friday night. Our water / sewage was plumbed into the mains so that was easy, as were the electrics (separate to the house).
Re the siting, we had ours on a patch of compacted hardcore, so that it had stability for the feet and also put various slab paths down, so that we could wade through the sea of mud in the winter (you want to avoid mud getting inside as much as possible). Sheltered if at all possible - I can't comment on gale force winds but ours did use to gently rock at 40/50mph, not ideal.
Good luck!
