Here is the Class A Aurora. Very Nice. Very spacious. We can't tow a car behind - they won't allow it. But this could easily travel and sleep all of us. It is the same price as the Class A next to it, but bigger and gets the same gas mileage.
Here's the cost breakdown.
Projected 2500 mile round trip to Grand Canyon.
Cost of Diesel 40' RV (7 Days and 700miles) = $2600
1800 xtra miles @ .35 = $630
Tax = $323
Projected Total = $3553
