"It's really fun when we first get there and we turn on the lights and play the music," said Moeller, 46. The Rocky theme blares after victories. After a loss, it's Taps.
"A lot of people think we're there as part of the Eagles."
Moeller grew up at the Jersey Shore on Long Beach Island and is a partner in Callan & Moeller Construction, a builder in the Ocean County resort. A fan since birth, he started attending all of the Eagles' home games more than 20 years ago and now has 14 season tickets at Lincoln Financial Field.
"That way the kids can each invite a friend to all the games, and that leaves a few seats for us to invite some of our friends," Moeller said, referring to himself and his wife.
Four years ago, Moeller went to an RV show, ostensibly just to browse. He returned with the behemoth now known as Eagle One.
"It was a bit of a shock," Monica Moeller said, "but we all got into the idea."
Each year since, Patrick Moeller has added more decals, more lights and extra accommodations. In addition to having a kitchen, a bathroom and six beds, the RV is equipped with four TVs, a grill, and a portable fire pit for making s'mores. In all, Moeller has sunk about $120,000 into Eagle One, which has been to all but two regular-season away games since it was purchased.
Rolling onto the parking lots of faraway stadiums in a massive RV emblazoned in Eagles green draws considerable attention. On Sunday, after the Birds dominated the New York Giants at the Meadowlands, angry fans pelted the Moellers' RV with beer and ketchup bottles. In November, Seahawks fans decorated Eagle One with eggs after Philadelphia's victory in Seattle.
"It's insane," said Emily Moeller, 14, who attends Westfield Friends School in Cinnaminson.
She added that plenty of fans gave them the finger, too. "It's just a crazy van, but it's a lot of fun," she said.
