A home is what you make of it, and it sounds like you have a wonderful home. Acreage in the Smokeys, how does it get better than that??
I put a mobile home on the 10 acres I bought here in Florida, and loved it. I did eventually build a site built house on here and sold the trailer, but if that hadnt of happened, I would have been just fine in my mobile home. It was very comfortable, a roof over my head, reasonable electric. It was great.
Ive never been much worried about what other people say about my situation. Unless they are paying my bills, they have no right to. As long as you and your family are happy, thats whats most important.
