It's fun, but Internet access not there yet (Score 5, Informative)

There's some good and bad sides to this. I actually tried this out about 3 years ago, wanted to travel while I'm still young and can do more. Me and the wife bought a 35' fifth wheel, moved out of the apartment, and put excess stuff in storage. After about 6 months, we moved out of the RV and back into another apartment. (Kept the RV though, still like to travel!)

The good:
- Having a new backyard every day/week was great.
- Met a lot of friendly people along the way. Many having dinner outside their RV would frequently ask if we wanted to sit and eat with them when we were walking around the park. In turn, we always tried to do the same when we had cooked something.
- A lot of experienced RVers and full-timers are more than willing to help out with issues you might have, as long as you're open to it.
- Seeing the country is great fun, especially the out of the way areas.
- On some days it feels like a full-time vacation (even when working).

The bad:
- High speed Internet access was spotty/unreliable. Being in a rural area, you may be familiar with this already, but when traveling around in an RV to random campsites and rest areas, you find out rather quickly that anything above 3G is still iffy on the open road. Don't count on the coverage map saying 3G or 4G is available in the middle of nowhere, especially if you have time-sensitive work you need to submit.
- Most campgrounds (i.e. RV-oriented campgrounds, not state parks and such) will offer wi-fi access, but it may be spotty, slow speed, or unreliable. And the campground office tends to either be empty when trying to find someone to tell there's a problem with the wi-fi, or if a person is there they usually aren't sure about the wi-fi setup or how to troubleshoot/reset it.
- If you travel a lot (i.e. don't hook up in one place for more than a few days) you will spend a lot on gas. And if you do stay in one place for a period of time, don't forget to account for campground fees.
- Most trailers aren't made for "permanent" living. You'll notice this most with the walls and lack of insulation, especially in peak summer and winter months. Quality counts here.

You'll definitely want to budget things out though, as you can easily spend a lot more than you would in mortgage or rent. Joining Good Sam helps some, committing to a place for 2-4 weeks at a time can help out more with campground prices. Some campgrounds will even let you do odd jobs to help decrease the "rent", but you'll usually find that "regulars" that have been there for extended periods already are doing those jobs. If you do commit to full-time, let your insurance agent know - most major carriers can convert your homeowners/renters insurance into an equivalent "full-timer" RV policy so you'll have coverage on the stuff in the camper.

In short, if you like to travel it's a good experience. If you don't like camping out, you won't have a good time (modern RVs are comfortable, but you still need to remember it's camping out, and you won't have all the amenities of a regular apartment/house). Also depending on how much you need an Internet connection, how fast you need it, and how often you need it, you may not want to commit to it full time. At least, just yet. As the infrastructure and reliability continues to improve, this will become less of an issue as time goes on (I'm sure it's improved some in the 2-3 years since we did it).
