hi, i am new at this whole thing but i really want to tour the states with my friend, im from and live in Scotland. is it possible to hire an RV and start somewhere in Houston, work my way through to Miami, Orlando, Washington, New York, Cleveland, Chicago, San Fransisco, L.A and finish up in either Vegas or Pheonix?? if this is possible how long would it take? what would the fuel be like? and can a RV be hired in one place and dropped off in another? or would i be better splitting this into several holidays? or any suggestions? please this has been on my to do list for a while. any help is much appreciated as my geography is shockingly bad and all i have to go on is google map
