I am planning a two-week, cross-country drive with the family and our dog. Boston-California-Phoenix-Texas-Boston. I am looking for recommendations for a good vehicle to rent. Was thinking of renting an RV, but all RV rental companies I can see only give you 100 free miles per day and around $0.35 per additional mile. Our trip should be around 7000 miles just getting from once city/state to another. At 14 days that is only 1400 free miles, adding almost $2000 onto the cost of the rental (already around $200 per day). I was thinking about renting a 12 passenger Ford Transit Van. Spacious with unlimited miles. But I wasn’t sure the seats could be removed and configured in a way for my kids to stretch out and sleep and still have room for the dog/luggage. Anyone have any recommendations?
