I lived in a 33ft travel trailer for a few months out in Phoenix. A lot of people out there live in rv's or trailers, its cheaper and you can travel. I will never do the rv thing again until my kids are grown and dh retires. I would however live in something like a double wide trailer.
I live in one now and I mostly like it. I like it a lot better than an apartment since the neighbors are not right next to your bedroom. I would prefer a house, but a mobile home is still pretty nice. I have lived in one when I was in elementary school too.
We are looking at living in one til we get our house built. They make excellent temporary homes and some are/can be really nice. We want certain things in our forever home that can't be accomplished in a mobile home/trailer.
I have a modular home. Some say it's called a mobile home some don't. I say it's my home and I love it. It's three bedrooms, three full baths two car garage the master bedroom is huge. You can fit three queen beds in there. There's two in there now. We have a walk through closet that is as wide as the room. My bathroom has a huge spa tub. We have a fire place but never use it. It's too hot.
