What owners report
Summarized from Reddit and owner forums — not a first-hand test.
The Keystone Arcadia 3660RL is the value play in the full-size fifth-wheel space. Its rear-living floorplan puts the lounge and big windows at the back for a bright, open feel that owners genuinely enjoy, and at $88K it's a more affordable way into a spacious, residential-feel fifth wheel than the Grand Design Solitude or Jayco Pinnacle flagships. Keystone's enormous dealer network also means parts and service are easy to find almost anywhere.
The concern is build quality, and some of the Arcadia complaints are more than cosmetic. Owners on keystoneforums.com have reported needing to replace 18 roof trusses built from 1x2 material that couldn't hold a person's weight despite a walk-on rating, along with half-uninsulated roofs and sagging pullouts on affected units. Electrical defects show up too — reversed AC fan wires, incorrect compressor connections, fried thermostats, defective bedroom GFCIs, and non-functional solar and radio systems on some new trailers. Add new-unit leaks, falling trim, and shower cracks, plus repeated reports of Keystone declining warranty help, and the value comes with real risk. Like any fifth wheel this size, it needs a one-ton (often dually) truck.
The Arcadia 3660RL is for budget-conscious buyers who want a big rear-living fifth wheel and are prepared to inspect aggressively and possibly fight for warranty coverage. At $88K it undercuts the premium competition by $7-27K. Against the Grand Design Solitude 3540GK it saves money but gives up Grand Design's stronger build reputation and customer support; against the Jayco Pinnacle it's cheaper but less refined and less consistently built. Buy it for the floorplan and price, but commission a thorough independent inspection — especially of the roof structure and electrical — before you commit.
