The Tiffin Phaeton in the Pacific Northwest

The sweet spot of the Tiffin lineup — and the coach I get asked about more than any other. Here's what a specialist wants you to know before you buy or sell one in Washington, Oregon, Idaho, or Alaska.

Talk Phaetons With Jonathan
Why the Phaeton

The best-seller for a reason

For years the Phaeton has been one of the best-selling luxury diesel Class A coaches in North America. It sits in the sweet spot: real luxury-coach construction and ride without the flagship price of an Allegro Bus or Zephyr.

For Northwest owners specifically, the 35 CH and 37 BH lengths thread mountain passes, state park sites, and coastal campgrounds that 45-footers simply can't. That's half my buyer conversations right there — matching length to how you'll actually travel out here.

2026 Floorplans

Four floorplans, four different owners

35 CH

37' · rear bath · triple slide

The maneuverable one. My default recommendation for Northwest couples who camp beyond the interstate.

37 BH

38' · bath & ½ · triple slide

Adds the half bath without much length penalty. Strong all-rounder.

40 IH

41' · bath & ½ · quad slide

The volume seller — space for full-timers while still fitting most premium parks.

44 OH

45' · bath & ½ · walk-in closet · quad slide

Maximum Phaeton. Residence-grade storage for serious full-time living.

Used Market

Buying a used Phaeton up here

The used Phaeton market in the Northwest is active but thin — good coaches sell fast, and wet-climate storage history separates the buys from the mistakes. Covered storage, clean roof and slide seals, documented chassis service, and honest generator hours are what I verify before a client wires money.

Phaetons hold value well against the broader Class A market, which also means overpriced listings sit while fairly priced ones vanish in days. Knowing the difference is the job.

Phaeton vs. Allegro Bus

The question everyone asks

Same Cummins L9 / Allison / PowerGlide XC foundation in 2026. The Allegro Bus buys you a higher trim ceiling, more basement storage, and the new PowerDrive steering column; the Phaeton buys you most of the experience for meaningfully less money.

My short version: if you're comparing equal-year coaches and the budget covers both comfortably, drive both. If you're stretching to reach the Bus, get the better-condition Phaeton instead.

Phaeton FAQ

What buyers ask me

Is the Tiffin Phaeton a good motorhome?

It's been one of the best-selling luxury diesels in North America for years — Tiffin build quality on a proven Cummins/Allison/PowerGlide platform, with resale value to match. The honest caveats are model-year specific; ask me about the year you're considering.

What does a Phaeton cost?

New pricing changes with options and model year — get current numbers rather than internet folklore. On the used side, value depends heavily on year, floorplan, mileage, and storage history; I'll give you a real number for a real coach, free.

What should I check on a used Phaeton?

Roof and slide seals, water intrusion evidence, tire date codes, generator hours, and complete chassis service records — plus Northwest-specific storage history. A Tiffin-specific inspection catches what generalists miss.

Where do I find one for sale in Washington?

Dealer trades, consignment lots, and private sellers across the region — and the good ones move fast. Tell me your floorplan and budget and I'll flag coaches worth chasing, including off-market ones.
