What owners report

Summarized from Reddit and owner forums — not a first-hand test.

The Thor Delano 24FB pairs the refined Mercedes Sprinter diesel chassis with a compact, drive-anywhere footprint and a Murphy-bed layout that opens up the living space by day. Owners love the Sprinter side of the equation — around 15 mpg, an easy and maneuverable drive, and the diesel range that makes it a strong long-haul tourer. With auto-leveling jacks and a diesel generator on many builds, it's a genuinely capable rig, and it delivers a premium Sprinter experience below Airstream Interstate money.

The house side is where Thor's reputation catches up with it. Owners report leaking water pipes, cracked side windows, and auto-leveling jacks weeping hydraulic fluid, along with water getting in through the door and steps in the rain and a bunk skylight that bakes the interior. Cooling can struggle in direct sun (some owners can't get below 85F parked out), the flat fresh-water tank sloshes water out while driving, and there's a list of nuisance defects — a master cutoff that won't shut off, an awning cap that falls off, a dead propane gauge, and orange-peel paint on the front bumper. The common refrain is that Thor's QC should catch this before it leaves the factory.

The Delano 24FB is for buyers who want the Sprinter diesel's refinement, economy, and range and are willing to sort out first-year bugs to get it at a lower price than the premium vans. At $175K it sits well above the gas ProMaster-based Thor Sequence 20A — you're paying roughly $70K for the Mercedes chassis, AWD availability, and diesel range. Against an Airstream Interstate it saves serious money but gives up Airstream's build quality and resale. Buy it for the chassis and the economics, do an exhaustive PDI of the plumbing, windows, and leveling system, and keep expectations realistic about Thor fit-and-finish.

What owners like

Common complaints

  • −Thor's quality control is the recurring complaint — owners report leaking water pipes, cracked side windows, and auto-leveling jacks leaking hydraulic fluid
  • −Water intrusion is a theme: rain entering through the door and steps, and a bunk skylight that lets in excessive heat
  • −Reported nuisance defects include a master cutoff switch that won't turn off, an awning cap that falls off, and a non-working propane gauge
  • −Exterior paint quality complaints include orange peel and spotting on the front bumper
  • −Mercedes diesel service is pricier and less widely available than gas-engine alternatives
  • −At $175K it's a big spend, and Thor's QC reputation makes that price harder to swallow

Questions owners ask

What chassis is the Thor Delano 24FB built on?
The Mercedes-Benz Sprinter with a diesel engine, which is why owners praise its fuel economy (around 15 mpg), highway refinement, and long-haul range. The trade-off is that Mercedes diesel service is more expensive and less widely available than the gas-engine ProMaster used in Thor's cheaper Sequence.
How reliable is the Thor Delano 24FB?
The Sprinter chassis is excellent, but Thor's house-side quality control is the weak point. Owners report leaking water pipes, cracked side windows, auto-leveling jacks leaking hydraulic fluid, water intrusion through the door and steps, and cooling that struggles in direct sun. Expect a shakedown period and inspect plumbing, windows, and the leveling system thoroughly before buying.
Delano 24FB or Thor Sequence 20A — what's the difference?
The Delano is built on the Mercedes Sprinter diesel and runs about $175K; the Sequence is built on the gas Ram ProMaster and runs about $105K. The Delano gives you better fuel economy, longer range, AWD availability, and a more refined drive, while the Sequence is far cheaper to buy and service. Both share Thor's QC reputation, so the choice comes down to chassis and budget.
Can two people boondock comfortably in the Delano 24FB?
For a couple, yes — the diesel range, generator, and auto-leveling help, and the Sprinter chassis is at home off the beaten path. But watch the fresh-water tank, which owners criticize as too flat and prone to sloshing water out while driving, and plan for the cooling limitations in direct sun. It's better for touring with periodic refills than long static off-grid stays.
Is the Delano 24FB worth $175K versus an Airstream Interstate?
It's a value-versus-prestige call. The Delano gives you a Sprinter diesel van for tens of thousands less than an Airstream Interstate, but it gives up Airstream's superior build quality, fit and finish, and class-leading resale. If you want the Sprinter experience on a tighter budget and will accept Thor's QC quirks, the Delano makes sense; if longevity and resale top your list, the Airstream justifies its premium.
