Heartland Bighorn 3375SS vs Keystone Arcadia 3660RL

Heartland Bighorn 3375SS

• ✓Road Armor suspension absorbs bumps better than most fifth wheels
• ✓Heartland's build quality rivals Grand Design at a lower price point
• ✓Central vacuum system is a surprisingly useful full-timer feature

Keystone Arcadia 3660RL

• ✓Center kitchen island provides serious counter and prep space
• ✓Commercial-grade vinyl flooring stands up to RV life better than carpet
• ✓Heated underbelly for comfortable 3-season+ camping

Heartland Bighorn 3375SS

• ✓Residential, full-time-ready interior with multiple slides, a real kitchen, and a comfortable living area that makes long stays genuinely livable
• ✓Strong value pricing around $85K undercuts comparably sized luxury fifth wheels while still delivering a high-end-feeling floorplan
• ✓Mid-profile fifth-wheel design lowers towing height versus full-height rigs, easing wind drag and clearance worries somewhat
• ✓Large holding tanks and residential appliances support extended off-grid or long-term hookups better than smaller bumper-pull trailers
• ✓The fifth-wheel hitch connection tows far more stably and confidently than a travel trailer of similar size, especially in crosswinds and on grades
• ✓Generous storage including a front pass-through basement gives full-timers room for tools, gear, and outdoor equipment
• ✓Heartland's owner community and parts support are well established, so help and replacement parts are easy to find

• ✗Water intrusion is the signature complaint — owners report bedroom slides leaking water into the floor, roof leaks from wrong sealant, and rotted slide floors
• ✗Interior materials feel cheap for the segment: flimsy wood trim falling off, low-grade furniture, and finish that doesn't always match the marketing
• ✗Heartland's customer service has frustrated owners; some report the company blaming the customer for 'lack of maintenance' rather than owning poor workmanship
• ✗The classic first-year shakedown applies in force — expect to find and chase down a long punch list of defects while under warranty
• ✗Dealers can be slow to complete warranty repairs, so a leak you spot early may sit unresolved through a camping season

Keystone Arcadia 3660RL

• ✓Rear-living floorplan puts the lounge and big windows at the back — owners love the open, bright living space
• ✓More affordable entry into a full-size luxury-style fifth wheel at $88K than the Grand Design or Jayco flagships
• ✓Keystone's huge dealer network means service and parts are widely available
• ✓Generous storage and a practical, livable layout for extended trips
• ✓Roof rated to walk on for maintenance access (when built to spec)
• ✓Solar and modern conveniences offered to support some off-grid capability
• ✓Lower price leaves budget room for the heavy-duty truck a fifth wheel this size requires

• ✗Electrical defects are reported, including reversed AC fan wires, incorrect compressor connections, and fried thermostats
• ✗Bedroom GFCIs reported defective and solar/radio systems non-functional on some new units
• ✗New-unit QC complaints include leaks under the sink and around rear windows, falling trim, and cracks in the shower
• ✗Multiple owners report Keystone declining warranty help and dealers offering no resolution
• ✗Fresh-water and appliance reliability issues reported, including a fridge that failed in its second season
