Discuss with the front office attendant. Semi-trucks park out back often.
Truck drivers are allowed to for a ten hr break cars I'm not sure of and please don't park your car in a truck parking spot as u will be asked to leave
If you are talking about the Flying J on Federal Way in Boise, Idaho, then, No. The Manager says you can sit inside and charge your phone; however, she told me that she did not want me parking in the parking lot overnight.
