The South Florida Sun-Sentinel said the recording artist read about Troop 631's story over the weekend. He had been in the area performing.
Troop leaders realized last week that a $5,600 trailer it had purchased in March after seven years of fundraising had been stolen, along with $4,000 in camping equipment stored inside.
The trailer had been parked behind the Tuskawilla Presbyterian Church.
The scouts had been planning a summer camping trip to Tennessee but, after the theft, that seemed unlikely.
Tom Daly, the church's liaison to the troop, called the outpouring of support the troop has gotten in the form of monetary and equipment donations "nothing short of miraculous."
"People's hearts were in the right place," Daly told the Sun-Sentinel.
"I will cut them a check for the difference and hopefully will allow the boys to make their trip," Kid Rock wrote via e-mail.
His publicist said Monday the singer wouldn't comment on his donation, however, he did say Rock was "very happy to help out."
