I am driving a 28 foot motorhome. Will I be able to park in the long term Parking lot at the Newark Airport? I will be gone for approximateely three weeks.

Yes we can. Just not this week. Too crowded for that large a vehicle. Call customer service for help on Monday 908 200 7165 x 2

They should be able to accommodate but to be sure call to find out. I had wonderful experience parking here and it was very convenient and easy..

Consider parking elsewhere and getting an Uber to the Airport.

I usually park off site. You'd have you call the lot you'll park in.
