Have done a summer travel assignment in an RV for the past 6 yrs & LOVE it. Moved up from a small class C to a large Class A. You might want to consider starting out in a smaller (read "more economical") unit to be sure you like that way of life. Read up on the RV sites for hints on picking the right unit. If you're self-contained (generator), you can dry camp overnight in most WalMarts, truckstops, large Cracker Barrels, etc while en route. Campgrounds around some VERY touristy areas (DC, for 1) don't have reduced rates for long-term campers - do your homework by using mapsonus, etc to be sure you can reserve a spot before you accept that great paying job in a big city! Good luck - excitedly planning for 2 assignments this summer/fall - Wyoming/Idaho & New Mexico/Arizona areas - quite a switch from our FL!!!
