I was in GDJ for 3 days, was met with cordial attendant who gave me close in tiedown, fueled plane for my departure, fine new FBO. It is a long way from the self serve pumps, so plan to pay the truck price (still fair for a Metroplex FBO). Enterprise provided a rental car delivered to the FBO with no trouble. GDJ is a good place stop to avoid the busier big city airports.

Stopped in today for some fuel and lunch. Line person was out at the pumps before I could get out of plane and put the fuel in for me. Plenty of crew cars available. Super nice people at the FBO, cheap gas and plenty of tow down spots.

GDJ is phasing out pumping your fuel as when the new terminal opens it will be too far from the pumps. So you might get fuel pumping service, or you might not. I suppose it depends on who's on duty.
