YouTuber Chopped the Roof Off an 8,900-Pound Trailer to Build a Luxury Two-Story CamperMotorBiscuitRahaan MazumderFri, September 18, 2026 at 12:30 PM UTCAdd us on GoogleWhen it comes to internet DIY vehicle conversions, Chay Denne—better known to his 2.4 million YouTube subscribers as President Chay—is in a league of his own. Whether he is building a fully functional SpongeBob Krabby Patty car or turning a 40-foot school bus into a two-story home, his fabrication projects always push the boundaries of backyard engineering.But for his latest summer project, Chay took on a build that absolutely dwarfs his previous automotive achievements: transforming an abandoned, 43-foot-long race car toy hauler into a sprawling, two-story luxury "Mega Camper.""This is now officially the biggest, most ambitious, most expensive project we've ever done," Chay admitted at the start of the build.The Can-Opener Roof ChopThe project started on Facebook Marketplace, where Chay and his brother Colby purchased the 8,900-pound, 43-foot gooseneck trailer. From a distance, it looked solid, but the interior told a completely different story. Neglected for years, the inside was filled with grass, trash, and a massive hole in the ceiling where a bird had built a nest. Because the trailer previously hauled race cars, the wooden floor was completely saturated with motor oil. "It stank," Chay noted bluntly.While the trailer already boasted eight-foot ceilings, that simply wasn't tall enough for the sheer scale of the floor plan they envisioned.AdvertisementAdvertisementTo make room for a second story, Chay completely severed the aluminum roof from the framing, hoisting it off with an excavator. "We're literally cutting the entire thing off just like a can opener," he laughed. He then welded in four-foot steel tubing extensions around the entire perimeter, dramatically raising the trailer's height, before wrapping the massive new skeleton in brand-new sheet metal using thousands of heavy-duty rivets.Instead of a flimsy metal roof, they framed a traditional residential-style pitched roof out of wood. "We want a new roof to be made out of wood where it's stronger and just easier to work with," Chay explained, capping the top with a heavy-duty waterproof vinyl membrane.Three Bedrooms, a Garage, and a Coffered CeilingThe layout of the Mega Camper is absolutely absurd, resembling a luxury condo much more than a travel trailer.Because of the three-foot roof extension, the team was able to build a multi-level floor plan. The front gooseneck area was converted into a massive master bedroom. In the rear of the trailer, they retained a functional garage on the bottom floor with a fold-down patio deck, while framing a second bedroom directly above it. A third sleeping area—a dedicated loft—was framed directly over the bathroom.Chay's brother Colby, the master carpenter of the family, took the interior to the next level. He hand-built 54 custom cabinet doors for the sprawling kitchen and engineered a stunning, dark-stained coffered ceiling for the main living area.AdvertisementAdvertisementTo keep costs down, the brothers avoided the massive expense of real stone in the kitchen. Recalling the $7,000 he spent on porcelain counters for his previous bus build, Chay and Colby ordered acrylic slabs online for just $2,000. After cutting them to size with a standard table saw, gluing the edges, and spending six hours sanding the seams, the acrylic looked exactly like high-end quartz. "Why did I pay $7,000 for my bus countertops when we could have done this for two?" Chay joked.The 4-Week DeadlineFor the utilities, the camper was outfitted with an immense amount of infrastructure, including 1,000 feet of electrical wire, three individual 36,000 BTU mini-split AC units to cool the different zones, a fully tiled bathroom with glass shower doors, and a massive 100-gallon black water tank."To save money and time, we're only doing a black tank in this camper," Chay explained, noting that the gray water from the showers and sinks bypasses a holding tank and routes straight to a drainage valve.What makes the build even more impressive is the brutal time crunch the crew was under. They had entirely booked a family vacation to Myrtle Beach six months in advance. "This isn't some made-up YouTuber deadline; we paid $2,000 for these spots 6 months ago," Chay emphasized.AdvertisementAdvertisementWorking through 95-degree heat, the team barely finished the interior trims and managed to spray the massive rig with a fresh coat of white paint just in time to hook it up to their Ford F-350 and hit the highway. Considering it started as a rusted, oil-soaked storage box, the Mega Camper is easily one of the most impressive heavy-duty vehicle transformations on the internet.
