Marty, I just moved my daughter to Newark DE.
Rented a 1 way 16' truck and trailer to tow her car, from Penske, and made non stop drive in 15 hours.
Also used "Hire a Helper" a moving company who finds local movers for hire, who would meet us after we got to DE to carry everything up the 3 flights of stairs to her apartment.
They charged $200/hr, but to me, it was worth paying the money over getting a back injury at my age.
They were done in 2 hrs.
Flew back from Philly to O'Hare to finish the trip.
