The Tiffin Allegro Bus in the Pacific Northwest

Tiffin's legendary luxury pusher — now with the new PowerDrive steering and, for the first time, a two-bath bunk floorplan. Here's the specialist's view for buyers and sellers in Washington, Oregon, Idaho, and Alaska.

Why the Bus

The coach Tiffin's reputation was built on

The Allegro Bus is where Tiffin puts its best: top-tier cabinetry and trim, the deepest basement storage in the lineup short of the Zephyr, and for 2026 the new PowerDrive enhanced steering column — a real drivability upgrade you feel on Northwest mountain grades and crosswinds.

The new 45 BP floorplan matters too: two full baths and mid-coach bunks. It's the first Bus genuinely built for families and grandkids — and I expect it to be scarce in this region for a while.

Used Market

Buying a used Bus up here

Used Allegro Bus inventory in the Northwest is thin and moves through consignment and private sale more than dealer lots. On coaches at this level, maintenance documentation is everything: chassis service history, aqua-hot or heating system service, slide and roof seal condition, tire age, and how it was stored through our wet winters.

I inspect and value Bus listings across all four states — and when the right coach isn't here, I source from outside the region.

Bus vs. Phaeton

Worth the step up?

Same 2026 powertrain as the Phaeton. You're paying for trim, storage, PowerDrive, and prestige. For some owners that's exactly right; for others the Phaeton is 90% of the coach for meaningfully less. Condition and year beat badge — I'll tell you which side of that line your budget lands on.

Allegro Bus FAQ

What buyers ask me

What's new on the 2026 Allegro Bus?

PowerDrive — the enhanced steering column that noticeably improves handling — and the new 45 BP two-bath bunk floorplan aimed at families.

What does an Allegro Bus cost?

New pricing moves with options and model year; used values swing on condition and documentation. Skip the internet folklore — I'll price a real coach for you, free.

Allegro Bus or Phaeton?

Same platform in 2026. The Bus buys trim, storage, and PowerDrive; the Phaeton buys value. If reaching for the Bus means an older or rougher coach, take the better Phaeton.

Where do I find one in the Northwest?

Consignment lots and private sellers more than dealer inventory. Tell me your floorplan and timeline and I'll flag what's actually worth seeing across WA, OR, ID, and AK.
