it will always feel like a small step above camping.
Say what? I don't know where you've been staying, but none of what you said is true. RV parks, unless they're wilderness campgrounds, always have electric, water and sewer connections and many newer RVs have 10-12 gallon hot water tanks which a lot more hot water than my wife and I have ever used at one time.
Not something you will want to do for several years.
Says who? The longer you're on the road, the less inclination you'll be to ever go back to bricks and sticks and having your house nailed to the ground. We've been on the road for three years and found that many of our problems with traditional housing stem from a lack of convenient mobility.
Most generators will run an A/C unit on an RV just fine. If your RV has two A/C units most likely your generator is already sized for the load. The only time we've ever run ours is when we stopped at a rest area and wanted to take a nap or make lunch.
For the OP I have sections on wifi, satellite and wireless internet coverage. Right now we get high speed to our 5th wheel from the cable company, just like we did at the last two parks we've stayed in.
And as far as comfort goes, you have to learn to live in less space but the space you have is better organized. And there's someone else taking care of the yard work, cleaning the pool, grooming the golf course and stocking the bar.
Full time RV living is more comfortable and way more convenient than you might imagine. It's not a great choice if you have kids, but my friend up the street is a Unix admin for a hospital chain and he's lived in RVs for the last 10 years. You couldn't get either one of us back in a house. Traditional housing sucks in comparison.
