Keystone Fuzion 421

The 13-foot garage is the headline here. Enough room for full-size toys without sacrificing the livability you'd expect from a rig this size. Back inside, a King bed and fireplace give the front bedroom a surprisingly residential feel, while the outdoor kitchen means you're not stuck cooking inside after a dusty day on the trails. Keystone built the Fuzion line with adventure use in mind, and the 421 reflects that with construction and layout choices that hold up to real-world use, not just showroom walkthroughs.
