StrongholdVBL™ Vacuum-Bond Lamination is the superior construction process exclusive to Jayco's recreation vehicles. EVERY sidewall, rear wall and slide room wall is bonded together for a minimum of 16 minutes under 144 tons of pressure to create the lightest yet strongest construction available in the RV Industry it's part of the Jayco Difference.
We screw down 3/8" roof decking at each seam, which creates a more firmly secured structure and reduces the chance of fasteners coming loose and puncturing the rubber roof material.
Competitors staple their decking, which is not as strong or as reliable as screwed construction.
Jayco uses oversized nail plate joint fasteners on both sides of the trusses, making for a much tighter truss with less chance of movement.
Competitors use smaller nail plates, and in most areas, only use them on one side of the truss, increasing the likelihood the roof will flex.
The Magnum Roof System uses 2 x 2 vertical studs, strategically placed to maximize load capacity. Nail plates also are used on both sides of the vertical stud to further enhance strength.
Competitors use a 1" piece of aluminum as their vertical support, which provides less strength in important areas.
The 2 x 2 vertical studs provide smoother edges along which to run wiring, greatly reducing the risk of electrical shorts.
With the 1" aluminum piece and its sharp edges, our competitors' roofs are more likely to have electrical shorts.
Between the roof and slideout openings, we use 7" header beams, a more acceptable material used in home construction for load-bearing beams.
Competitors use a 2 x 6 piece of lumber, which creates a weaker 5 1/2" beam.
The Magnum Truss Roof System withstood 4,500 lbs., showing that Jayco's exclusive roof construction can hold a 50 percent heavier load than the competition. This strength translates into durability and is a result of superior quality construction.
