Other floor plans with a similar body style, feature mix, and price range, prioritizing other manufacturers and brands.
The Keystone Fuzion 419 leads with a front bedroom layout, keeping your sleeping space separate from the garage action, and backs it up with a loft, bath and a half, and two entry and exit doors that make life with a full crew much smoother. Owners are consistently impressed by the sheer size of the garage and how much it can swallow, and more than a few have noted the Fuzion 419 tows with more stability than shorter fifth wheels they've owned before. The bath and a half is a genuine quality-of-life feature in a toy hauler, where morning routines can otherwise turn into a bottleneck. Just know going in that Keystone's build quality has drawn mixed reviews from owners, so a thorough PDI and a good dealer relationship go a long way with the Fuzion 419.
