Me and my boyfriend are from the UK. We are planning a road trip from Boston to San Francisco in October stopping in alot of different places along the way and goin down to Texas aswell. We are looking to go for about 3 weeks, would this be enough time? we also not sure what the best opstion would be travelwise, would it be better to travel by car and stay in hotels along the way or to rent an RV, what are the best websites to rent transport that can be dropped off in different parts of the country. Any suggestions and tips would be greatly appreciated!
