15' 6" Cargo Area
Dual Entry Doors
Half Bath in Garage
Loft
Kitchen Island
HappiJac Electric Queen Bed

Explore new places with your toys with this fifth wheel that offers a separate garage from the main living and kitchen area and turns into an extra living space once you have unloaded your toys. You can easily set up the rear convertible sofas below the electric queen bed to rest and relax before heading out, and the second entry door plus the half bath provide convenience. The main living and kitchen area is spacious with two slides, and the SuperSofa offers heat, massage, recliners, cupholders and LED lighting. You can watch the 4K Smart LED HDTV with a fireplace below and visit with the cook. The kitchen offers a GE Profile Series 30 in. residential convection microwave with built in air fryer, an island, a pantry and a 17 cu. ft. 12V refrigerator. You will find shoe storage under the interior steps as you head to the inventive side-aisle bath with walk-in shower. And you'll sleep like royalty in the master bedroom with a king bed. Be sure to enjoy the two electric awnings when hanging outdoors, plus the party deck offers a place to relax and entertain above ground.

With any Seismic Luxury Series fifth wheel toy hauler by Jayco, you will enjoy the versatile garage that offers a rear ramp door and patio with anti-slip, non-skid flooring, a Tuff-ply, rubberized garage floor liner, and the Industry's first 2" block-foam fully insulated garage floor. The mandatory 5 Star Handing package gives you MORryde CRE-3000 rubberized suspension, Dexter axles with Nev-R-Adjust brakes, E-Z Lube hubs and 4,000 lb. leaf springs, and a MORryde pin box and more. More standout features include the removable three seasons garage wall/doors, the wireless remote control system which includes Bluetooth wireless interior controls, the fresh water drinking system, and the list goes on and on! Choose a Seismic Luxury Series because there isn't anything better!

Appreciate your help
Just wanted to let you know how much we appreciate your help with the purchase of our new Airstream – FYI Arlette is thrilled! You and your team at Vogt really did a wonderful job of communicating and supporting us through the long distance transaction.
Special thanks to Gil, and Andy for their work

Arlette
Very helpful
Dawn and I want to express to you what an excellent experience we had with Vogt.
We began this search back in the fall and came back two times to visit with Tim and each time even though we didn’t buy and told him we would need to wait he smiled each time and was still willing to answer any questions

John
Excellent service and cheerful attitudes
Yesterday I rolled in to your Service Center at 5:10 pm with a lighting malfunction on my vehicle to the trailer.
The service guy called some of your guys on their way back to the shop from a RV show. They were told I would be waiting at the north store when they arrive in about 30 minutes. The guys
