NTs can't comprehend the joy of solitude, so they always worry about going 'stir crazy'. I don't see a down-side to going solo.
You have communications, money for emergencies, the jewish safety net...
You may want to take little jobs along the way. I found that there were always people offering me room and board and a little pocket money in exchange for odd jobs, or seeing if I could help for haying season. I always tried to stay off the interstate, and on the smaller highways so I could see the real America. People were very nice and understanding everywhere I went outside of cities.
