Seismic is one Jayco’s most versatile fifth wheels thanks to its spacious garage. The HappiJac electric bed lift turns the cargo area into a bedroom for the guests, while 2,500-lb. floor-mounted D-rings make Seismic a toy hauling machine. Inside, this toy hauler packs everything you would expect in a traditional fifth wheel, like a full-featured master suite, top-of-the-line kitchen and state-of-the-art home theatre system.

* The weights of certain options and/or option packages are not included in the UVW listed in the specification charts. The addition of options will decrease the CCC.

Weight Definitions

Unloaded Vehicle Weight (UVW): Sometimes referred to as "Dry Weight." UVW means the typical weight of this trailer as built at the factory. The UVW, as used in product literature and other promotional materials, does not include cargo, fresh water, LP gas, options or dealer-installed accessories.

Gross Vehicle Weight Rating (GVWR): GVWR means the maximum permissible weight of the trailer, including the UVW plus passengers, personal items, all cargo, fluids, options and dealer-installed accessories. The GVWR is equal to or greater than the sum of the UVW and the CCC.

Cargo Carrying Capacity (CCC): CCC means the maximum weight of all passengers, personal items, food fresh water, LP gas, tools, other cargo and dealer-installed accessories that can be carried by the trailer. CCC is equal to or less than the GVWR minus the UVW.

It is important for your safety and enjoyment that your tow vehicle be adequately sized and equipped to tow and handle the GVWR of the RV you select. Review weights and ratings of your tow vehicle and consult a competent advisor for questions or advice. Whether you are new to RVing or a veteran, get a feel for the performance of your tow vehicle and the RV together before heading out on the roadways. When you tow an RV, you must drive differently than you do when driving a single vehicle. Practice hooking up, driving, backing up and braking in a safe environment or seek out professional instruction.

See specification chart above, Jayco affixes a weight label to each new RV which lists weight information for that vehicle.
