Generations of Family Fun

Starts with Peace of Mind

At Jayco, we build our RVs to handle every adventure, which is why we can offer an industry-leading 2-year limited warranty. Our dedicated production team includes Amish craftsmen who build with well-honed woodworking skills passed down for generations. We make sure we take the extra steps to build high quality products that are durable and use the most advanced construction techniques.



Jayco builds on custom-sized frames, designed specifically for each floorplan. Other manufacturers use stock frames, stretching and welding the frame to fit.

Full-width outriggers
  • We build on full-width outriggers that are 4-6 feet apart (vs. 8 feet) to better support the weight of the wall.
I-Class cambered structural-steel I-beams

Jayco uses a unique molded, one-piece design to prevent the unit from twisting; competing three-piece I-beams can warp over time at the welded seams.

Fifth wheel frame
  • The frame over the truck bed is built on a superior 2" x 6" tube perimeter structure to better support the bedroom sidewalls. Competing fifth wheels have a smaller frame; these manufacturers add a sidewall support seam to compensate for expansion joints.
Magnum Truss Roof System

In a side-by-side comparison test, Jayco's exclusive Magnum Truss Roof System withstood 4,500 lbs. - 50 percent more than other roofs. The difference?

  • Jayco uses 5" arched, stamped steel roof trusses, 2" x 2" vertical studs and oversized nail plates to maximize the roof's load capacity.
  • Then, we screw down 3/8" roof decking at every seam, a process that is more durable than stapled construction.
  • Finally, our one-piece, sidewall-wrapped DiFlex II material provides the ultimate in leak protection.
Wall Construction
  • Pinnacle features durable, vacuum-bonded, laminated sidewalls with smooth Gel-360 fiberglass exteriors that provide long-lasting appeal.
  • Welded aluminum frames give Pinnacle a durable, lightweight structure.
Upper Area Construction
  • In the upper area of the fifth wheel floorplan, Jayco uses a double layer of fiberglass insulation behind the front cap, along with Flexfoil and fiberglass insulation in the floor, to provide extra warmth where it's needed most - in the bedroom.
Front Cap Construction
  • Jayco's aerodynamic front cap is engineered to withstand the rigors of the road. Paint infused and gel coated, this fiberglass cap features more support with 1/4" plywood bracing, not typically found on other fifth wheels.



Extend your camping season with the Jayco Climate Shield — the ultimate in weather protection. Designed for efficient heating and cooling, Climate Shield protects against extreme heat and extreme freezing — even when temperatures hit a high of 100° F or a low of 0° F.*

Dometic Climate Control

Dometic Climate Control
Jayco took five of its toughest towables to Dometic, the nation's premier climate control facility, where independent technicians put the Jayco Climate Shield to the test against extreme temperatures.

Independent Heat Testing

Independent Heat Testing
Each unit was subjected to 100° F heat for an 8-hour period. During that time, sensors were placed throughout the coach to measure the unit’s average temperature. The result—the Jayco Climate Shield maintained a comfortable temperature of 71° F.

Independent Cold Testing

Independent Cold Testing
Each unit was then subjected to 0° F temperatures for an 8-hour period. Temperatures dropped so low the tires frosted over, yet inside the coach, plumbing remained fully functional. When the test was complete, the same temperature sensors found that the Jayco Climate Shield maintained a cozy temperature of 68° F.

Water Tank Testing

Water Tank Testing
Following cold testing, technicians emptied the holding tanks to check for any final freezing. Thanks to a fully enclosed underbelly with forced air and radiant heat, the Jayco Climate Shield held up to temperatures as low as 0° F (-17°C).

*Unit was tested in 0 degrees F and 100 degrees F weather over an extended period of time in a controlled environment and all functions of the coach were fully operational. Testing was done in a completely controlled environment, therefore temperatures during testing may not represent actual temperatures in nature and cannot account for elements such as wind or moisture. In actual use, unit may not perform as well. Supplier of cooling components does not guarantee anything better than 20 degrees difference from ambient temperature. In addition, outside components are subject to freezing and require steps to properly insulate. Jayco’s warranty does not cover damage caused by freezing.
