I've read all the comments thus far so I might as well throw in my thoughts (in more or less random order). My wife and I have a class B (van-based) RV and we typically go out for a month at a time. Our goal is to experience the outdoors - State and National Parks, etc. Space is limited but we find it easy to deal with and it beats the heck out of motels and cheesy restaurants.
Safety - We have never felt unsafe in any campground we have been in. As far as I am concerned the major danger in RVing is being on the road with the other drivers who may or may not be functional.
Social interactions - For better or worse you meet all kinds of different people.
Internet - If you really need access for 40 hours a week, there are expensive satellite providers. I know nothing about them but check the tech forum here for info. For cell phone service we have Verizon. Excellent service near towns and along the freeways but as a rule, we find that the more interesting the place, the less likely you will have service.
Your process:
1. If you need internet access 9 to 5 M/F when will you travel? Will you be sitting in your RV every day pounding a keyboard? Why travel?
2. Just about everyone (including me) suggests renting an RV for a week as the first step. Why are you so opposed to that? You may find that there is some aspect of RVing that is a dealbreaker and a weeks rental is a small investment to find that out. A week of living in an actual RV at actual campsites is a far better test of your compatibility with RVing than living in a confined space in your home. Plus, if you decide that this is a route that you want to follow, you will know a lot more about what you need to have in an RV.
