Full time rv living

Thank you everyone for the advice. I guess I should have gone more in-depth. We are parking it in my in-laws back yard so that's why I was trying to figure out if you can hook up to a house. So if something happens during winter it will just be a walk to their house. Also we have been slowly downsizing over the past year from a 2500 sq ft house to 1000 sq ft now down to about 350 hopefully soon. We want to build a tiny home and live the minimalist off the grid life as much as possible so we aren't too worried about space. Also we have a 10×12 shed that will be going with us for storage. We were told to make sure the underneath of the trailer is very well insulated and someone said to put skirting up and hay bales underneath but I'm afraid that would attract critters?!
