What Owners Say

Based on 6,800 online discussions

The Grand Design Reflection 337RLS is one of the best-selling fifth wheels in the country, and it earned that spot honestly. The rear-living floorplan is open, bright, and stuffed with the storage owners obsess over, and Grand Design's mid-profile build reputation means a lot of people buy one and simply never have problems. It's the rig that converts travel-trailer owners into fifth-wheel believers — comfortable enough for full-timing and snowbirding, but lighter and shorter than the company's full-profile Solitude.

That size difference is the practical heart of the decision. At under roughly 9,000 lbs dry and about 33 feet, the 337RLS is towable by a well-equipped 3/4-ton, where the heavier Solitude really wants a dually. Be clear-eyed, though: the 'half-ton' talk you'll see online is wishful — owners report pin weight around 3,000-3,100 lbs and roughly 14,000 lbs loaded, so a 3/4-ton is the floor and many owners lean to a one-ton when fully loaded. It tows beautifully (owners praise the Andersen Ultimate hitch even in short-bed trucks), and the tankless water heater, auto-leveling, and residential touches make it feel premium. The asterisks are the same brand-wide ones: post-2020 quality complaints (appliance failures, trim falling off slides, outlets pulling out) and slow customer service, plus early-build Lippert axle seal issues before the switch to Dexter.

This is the sweet-spot rig for couples and snowbirds who want a roomy, well-built rear-living fifth wheel without stepping up to a dually-required Solitude. Against the Solitude, the Reflection is the value and towability play — most of the experience for ~$20K less and an easier tow. Against a Keystone Cougar or Jayco Eagle, the Reflection wins on build reputation and resale while costing a bit more. If you want a popular, proven, well-supported fifth wheel and you have at least a solid 3/4-ton, the 337RLS is one of the safest buys on the market — just budget for a careful PDI and the occasional first-year warranty annoyance.

What Owners Love

  • 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

Common Complaints

  • Despite 'half-ton' chatter online, owners report pin weight around 3,000-3,100 lbs and ~14,000 lbs loaded — that's a 3/4-ton-minimum trailer, and many lean one-ton when loaded
  • 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
