I've done TX to NJ 2x in the last 2 months. Only thing I recommend for the trip is a quart of 10-60 and a AAA membership (some levels have a waiting period so do it now). Also, these cars are not comfortable when your doing 800-1000 miles a day...could be just me as I'm a big boned fat ass, not sure any car would be comfortable on those stretches. Also, these cars suck as campers at rest stops, just saying.
Heed my AAA suggestion. If you go into lip mode or completely blow out a tire you will need to be towed. Ask me how I know that
