What owners report
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
Grand Design Reflection 337RLS
- ✓One of the most popular fifth wheels in America for good reason — the rear-living floorplan is roomy, bright, and packed with storage that owners consistently rave about
- ✓Lighter and shorter than the full-profile Solitude (under ~9,000 lbs dry, around 33 feet), so a well-equipped 3/4-ton can handle it where the Solitude needs a dually
- ✓Grand Design's build reputation is among the best in the mid-profile class — many owners report zero issues for years
- ✓On-demand tankless water heater, auto-leveling, and residential touches make it feel a step above the price
- ✓Strong resale — Reflections hold value well thanks to the brand's reputation and the floorplan's enduring popularity
- ✗Post-2020 quality grumbling applies here too — appliance failures (Furrion microwave handle switches, a full refrigerator replacement), trim falling off slides, and outlets pulling out of the wall
- ✗Grand Design customer service has drawn real criticism — owners report 10-month waits for repair reimbursements on brand-new units
- ✗Early-production units used Lippert axles with leaking grease seals before Grand Design switched to Dexter — worth checking on older rigs
- ✗Slide motor/actuator and leveling-jack failures reported by some owners (often dealer-covered, but still downtime)
- ✗Rear-living means no rear bedroom view trade-offs and a layout best suited to couples, not big families
- ✗At ~$82K it's a real investment, and even strong-resale fifth wheels depreciate
