What owners report
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
