I-Class cambered structural-steel
I-beams

[ Jay Flight, Eagle TT and Octane ]
I-Class I-Beam frame

1. One-piece I-beam:

Features a formed, one-piece design to prevent the unit from twisting; competing three-piece
I-beams can warp over time at the welded seams (n/a on Jay Flight SLX).

2. Integrated A-frame:

Runs through the main frame to prevent the hitch from buckling like competing tack-welded frames. (The Jay Flight seasonal trailer A-frames are not integrated because these units have a detachable hitch for long-term stays.)

3. Full-width outriggers:

Utilizes full-width outriggers, spaced 4-6 feet apart (vs. 8 feet), to better support the weight of the wall.

Norco NextGen Frame

[ Jay Feather / White Hawk ]
Norco NextGen Frame

1. High-strength steel:

Features the industry’s strongest strength-to-weight ratio thanks to a Norco NextGen frame made of high-strength, low-alloy sheet steel, electrically-coated finish and an interlocking design (n/a Jay Feather SLX).

2. Integrated A-frame:

Runs through the main frame to prevent the hitch from buckling like competing tack-welded frames.

3. Full-width outriggers:

Utilizes full-width outriggers, spaced 4-6 feet apart (vs. 8 feet), to better support the weight of the wall.

4. Huck bolts:

Provide up to ten times the fatigue strength of a conventional fastening system and can withstand 6,000 lbs. of force per bolt.

Fifth Wheel Frame

[ All Jayco fifth wheels ]
Fifth wheel frame

1. Fifth wheel frame:

Boasts a 2"x 6" tube perimeter frame over the truck bed to better support the sidewalls; some competing fifth wheels add a sidewall seam and expansion joint to compensate for less robust frames.

2. I-Class cambered structural-steel I-beam:

Features a formed, one-piece design to prevent the unit from twisting; competing three-piece I-beams can warp over time at the welded seams; on our drop-frame fifth wheels, we use a monster beam, 2" wider to support this high-torque area.

3. Full-width outriggers:

Uses full-width outriggers, spaced 4-6 feet apart (vs. 8 feet), to better support the weight of the wall.

4. L-brackets:

Creates a channel within the frame to secure the underbelly cover for a tightly sealed insulation barrier; some competitors attach the lining to the bottom of the frame, increasing the chance of rodents.

Motorhome Frame

[ All Jayco motorhomes ]
Motorhome frame

1. A custom one-piece, laser-sheared, tight-fit frame:

Optimizes weight distribution for a more durable foundation; extra heat shielding is added to the frame, and entry steps are secured to the frame instead of the floor.

2. Balanced driveshaft:

Features a balanced driveshaft to reduce shudder.

3. Full-width trusses:

Extends to the edge of the sidewalls to better support the weight of the wall; each truss design undergoes a pull test for added safety.

At Jayco, we know everything is riding on your frame. That's why we don't cut corners when it comes to your RV's foundation. We use some of the industry's strongest frames. Unlike other manufacturers who build on stock frames, every Jayco RV has its own custom-sized frame, eliminating modifying and welding that would otherwise compromise the foundation.


So what makes our frames so different? Jayco's commitment to superior construction.
