The rear-living layout is the headline here. Instead of cramming the entertainment area up front, the 321RSTS puts the living room at the back with a rear window that opens the space up considerably. Up front, the King bed sits east/west so you're not climbing over a partner in the middle of the night, and the full bath is accessible even with the slides in, which is a genuinely useful detail on travel days. Back in the living area, a fireplace, ceiling fan, and kitchen island with a farmhouse sink give it a residential feel that's hard to fake in a fifth wheel. Jayco backs it with a 2-year warranty, and the Climate Shield package. Fully enclosed heated underbelly, dual-layer insulation, and 100% residential plumbing. Means this one is built to handle shoulder-season camping without fuss.
