Daniel and Vincent Cantu said the 32-foot trailer was parked behind a business in the 13700 block of the Southwest Freeway between Sugar Creek and Southwestern Boulevards.
Surveillance video shows a black pickup pulling up to the trailer and hauling it away just before 3pm. The truck then drove onto Southwestern Blvd. toward the freeway.
"There's not a lot of people on the roads that day," Daniel Cantu said. "It's hard to miss a big black truck with a big white trailer on it on Christmas afternoon, and I trust that there are good people out there who saw something and would do the right thing and call us."
The trailer was full of thousands of dollars of equipment that Vincent Cantu uses to help out with promotional activities at the gym his brother owns.
Vincent Cantu is a permanently disabled Gulf War veteran who said he feels he can't function like he used to without his creative hobby.
The trailer was white with no markings, but you could see remnants of graphics that were once applied. It also had small safety stickers as well as red and white reflective strips. It had Texas license plate number 030-070H.
Anyone with information on the whereabouts of the trailer can call Vincent Cantu at 832-882-8181 or the Sugar Land Police Department.
