I did 22,000 miles in my old Dodge (78 Class C) and saw more of the USA and Canada than most people ever will in a lifetime (I'm not from North America). From taking a snowmobile up a remote mountain to watching a satellite launch in Cape Canaveral, staying on Indian Reservations in AZ and hitting Irish pubs in NY, all was done in good time. I even found time to get stranded in a blizzard in North Dakota, which was so cold it froze all the water tanks.
Mainly I'm just reminiscing about a simpler time in my life, but my one piece of advice is about getting the RV level on streets. Get yourself some flat pieces of wood, and a simple spirit level. Keep the wood in one of the outside storage compartments. When you've got to park on the street, just put the wood in the lower side of the street and drive up. Check your level and adjust as necessary. The advantage of this is that someone driving past won't notice quickly (because it's usually the footpath side that's lower), like they would with the jacks. And if you need to make a speedy getaway (for instance, seeing patrolling cop cars) you can just drive off the wood and go - easy enough to get some new pieces somewhere.
Other tips include : don't park in obvious places like recreation area carparks, and never park outside someones house. You want to get more 'public' buildings like churches, schools, retirement homes and telephone exchanges, but without going into a deserted area. Nobody is generally in these buildings at night and you'll be gone in the morning. Street parking/sleeping is a fun pastime once you get into it because you really feel you're getting away with something. The only time I had any problem was when I had the motorhome parked outside my apartment, and my elderly neighbour rang the cops on me. I wasn't sleeping in it (obviously) but was always tinkering with bits and pieces, so she thought I was. Most cops don't care and if you're courteous and leave when told it won't go any further. It was easier for me to play the dumb card because of my accent.
Good luck with it, and I'll file this one away as something to think about. I think I'd need ubitiquos internet to get a little better, but it's probably something to think about.
