RV Satellite Woes

I live in an RV and travel a great deal. I failed to anchor my DISH 500 in Louisiana and it died in high winds. I upgraded my receiver to a VIP 222K receiver and 1000.2 eastern arc set with two LNBFs for 61.5 and 72.7. Our travels have taken us west to Colorado and east to Maine. Eastern arc worked ok for the eastern arc, but as we got to Kansas and Colorado, it was necessary to switch to western arc?
1. Is it recommended to have two dishes which I can switch between for better...
