G'Day, My husband and I and our two children are looking to drive from LA-New York (or reverse) in October 2011 for 3-4 weeks. We would also like to spend approximately one week at each end of the trip to see the sights of LA & New York. Our options are to hire an RV for this period OR buy a used RV and then sell it when we are finished OR, a friend has suggested that perhaps someone may be interested in swapping their 4+ Berth RV in exchange for a vacation to Australia. Whilst it is still some time away, I thought I would start planning now and ask a few people on what the best option would be, both financially and given the time we are dedicating to the trip. Having not visited the US before, is it possible to do this trip, with a bit of sightseeing in between in the time frame of 3-4 weeks? Are there plenty of parks to stay in along the way? Any suggestions would be most welcome, thank you.
