The comforts and conveniences of home come with you no matter where your journey takes you.

Design that hits the mark

Beautiful colors, tiling, countertops, woodwork and fixtures make the Seismic master bath a functional and comfortable retreat.

Make a statement

With features like whole-house LED lighting, a painted front cap with blue accent lights and frameless, G20 dark-tinted windows make the Seismic a bold and eye-catching presence.

Your adventure companion

Generous dual-pane tinted (optional) windows with MCD® roller day/night shades can allow loads of natural light in or can make for a private and relaxing escape after a long day on the trails.

Soak in the outdoors

The 4212 Seismic’s side patio with a TV hookup expands the unit’s functional living area and provides yet another opportunity for enjoying the great outdoors.

Fit for a king

An optional king-size bed, walk-in closet, large TV, reading lights and MCD® roller day/night shades, you’ll feel like you rule the campground in the Seismic toy hauler.

Feels like home
