Starting out
quote:what would be the most practical/economical approach
There is such a wide range of RV available today that this is an impossible question to answer. The most economical RV for family use for week ends and vacations there is no doubt that the pop-up would be most economical. Next to that would be the hybrid. But only you can decide if that is also practical. That would depend upon your camping skills and the degree of comfort and amenities you want. On the other hand, for a family to live in fulltime you are sure to want more than either of those offer. The question then is one of budget. RV's come priced from used ones for less than $10,000 to new motorhomes that exceed a price of $1,000,000.
quote: We are going to sell our home and would like to live in something comfortable.
This is again something that we just can't answer without much more information. We have been fulltime now for six years in a motorhome that all of our friends believe to be too small, yet we have found it to be more than just comfortable. Then there is also the issue of where you expect to be in what kinds of weather. If you spend time in extreme heat or cold you will need much more insulation than if you plan to follow the weather.
quote:Can people move about in an RV while it is moving?
If you choose a trailer of any kind, it is not safe to have anyone in it while traveling. In a motorhome, limited movement can be done but not legally as seat-belt requirements do apply. Most of us do use the bathroom while traveling and also the refrigerator. But only in light traffic and we stay seat belted in the majority of cases. It has some risk to move about, but is usually safe if good judgment is used.

o camp grounds charge by the foot to accommodate you?
No. Some parks do have "big rig" sites that cost extra, but not by the foot. Most are based on what hook-ups the site has. The majority of RV parks have sites that all have water and electricity, and others that have sewer as well.
quote:What does WiFi mean?
That stands for "wireless fidelity" and refers to internet access via a wireless connection that can be accessed by a computer that has that capability. It might be free or for additional cost. Thus far, less than 1/4 of all parks have it available, but it is increasing rapidly.
I strongly suggest that you spend some time at your nearest RV show and learn what is available and at what price first. You would also be very wise to spend the money to join the RV Consumer Group.(
www.rv.org) They will provide you some much needed educational materials. And if you are thinking about full-time RV travel, you would be very wise to buy at least one good book on the subject to learn just what is involved. I would suggest either "Full-time RVing" by Jan & Bill Moeller and available from Trailer Life Press, or "Home is Where You Park It" written by Kay Peterson and available from Escapees RV Club (
www.escapees.com).
