Actually, our cash expenditure up the coast was a little over $2k for fuel in the RV, a hotel room at each stop, and moderate food. It is doo-able at this level but not terribly comfortable. And before you intend to pile four people in an RV - go through every imaginable detail such as making sure there isn't a snoring problem...everyone needs to be able to sleep well on this journey! For the advantages that the RV offers, it is disadvantaged by manueverability. A couple of the stops are very tight and one had us about two miles (and a ride in a taxi) away from the motorhome (that was tough). Our ground crew mgr. recommended having a van pulling the trailer and two hotel rooms up the way (and he's pretty experienced with motorhomes).
