What owners report

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

The Thor Sanctuary 19L is the budget-minded entry into a true compact Class B - under 20 feet, fully self-contained with a wet bath, and priced thousands below the Sprinter-based premium vans it shares a chassis with. Owners are drawn to its standout storage, its 460Ah lithium package, and the simple fact that it drives and parks like an oversized van. The vibe is practical and value-first: this is the rig for people who want into the Class B lifestyle without the six-figure premium that LTV or Winnebago commands.

Living with it surfaces the usual budget-coach tradeoffs. The bed draws the loudest complaints - short and firm, with reviewers openly warning buyers off it - and the wet bath, while genuinely usable, is tight. Thor's value-tier fit and finish means owners spend the first season chasing loose latches, trim, and hardware. One thing to get straight before buying: despite the affordable positioning, the Sanctuary line actually rides on the Mercedes Sprinter diesel chassis, which brings DEF, Mercedes service intervals, and dealer dependence - not the cheap-to-service Ram ProMaster gas setup some shoppers assume. Owners do report a strong 18-23 mpg and ample power for grades.

This is the van for the budget-conscious couple or solo traveler who wants real Class B self-containment and is willing to trade premium finish and a great bed for a much lower entry price. At roughly $98k it dramatically undercuts the $195k Winnebago Revel, which owners explicitly cite as the reason they chose it - and Thor's vast dealer network makes service far easier than with a boutique builder. The honest comparison: the Revel offers a proper 4x4, a far better build, and a bigger battery, while the Sanctuary 19L gets you self-contained and off-grid-capable for roughly half the money, as long as you go in clear-eyed about the quality and the chassis.

What owners like

+A 460Ah lithium battery package gives the 19L real off-grid endurance for a budget-positioned coach, letting owners run the fridge and electronics for days without shore power
+Priced well below the Sprinter-based premium crowd, owners specifically cite the Sanctuary costing far less than a comparably sized Winnebago Revel as the reason they bought
+Swivel captain's chairs and a smart electronics station make the small footprint feel livable as a daily driver and a basecamp
+Thor's huge dealer and service network means warranty work and parts are easier to find than with boutique builders like LTV or a defunct Roadtrek
+The wet bath with fold-down sink lets two people travel fully self-contained in a sub-20-foot rig - rare and a big draw for couples who want to skip campground bathhouses

Common complaints

−The bed is the most common gripe - reviewers flatly warn 'you won't like the bed in the 19L,' and owners note the rear sleeping area is short and firm
−Thor's marketing has muddied the chassis story - the Sanctuary line is actually built on the Mercedes Sprinter diesel, so shoppers expecting a cheap-to-service Ram ProMaster gas van should confirm exactly what they're buying
−Being a Sprinter underneath means Mercedes diesel service intervals, DEF, and dealer dependence - the cost-of-ownership reality clashes with the budget price tag
−Cabinet latches, trim, and small hardware are where Thor saves money, and owners report needing to chase down loose or failed pieces in the first season
−Tight interior means two people living aboard full-time will feel the squeeze - it's a weekender and trip van more than a long-haul home
−Resale lags the boutique brands - a used Sanctuary won't hold value the way an LTV or even a Winnebago does, reflecting the budget positioning

Questions owners ask

What chassis is the Sanctuary 19L really built on?

Despite its budget Class B positioning, the Sanctuary line is built on the Mercedes-Benz Sprinter diesel chassis, not a Ram ProMaster gas platform. That means strong fuel economy and power, but also DEF, Mercedes service intervals, and dealer dependence - confirm the exact chassis and engine on any unit before you buy.

Is the bed really that bad?

It's the 19L's weakest point. Reviewers openly warn buyers off it and owners describe the rear sleeping area as short and firm. Many add an aftermarket topper to make it tolerable, so factor that into your decision if you're tall or a picky sleeper.

How does it compare to a Winnebago Revel?

Owners specifically choose the Sanctuary because it costs far less - roughly $98k versus the Revel's $195k. The Revel gives you a proper low-range 4x4, a notably better build, and a bigger battery system, while the Sanctuary gets you self-contained and off-grid-capable for about half the money with more budget-tier finish.

Can two people really live in under 20 feet?

For weekends and trips, yes - the wet bath, galley, and 460Ah lithium make it fully self-contained. But full-timers feel the squeeze; the tight wet bath and firm bed wear thin over long stretches, so most owners use it as a nimble weekender and basecamp rather than a permanent home.

Is Thor's build quality a dealbreaker?

Not necessarily, but go in expecting budget-tier fit and finish. Owners across Thor models report rattles and loose latches and trim that need sorting in the first season. The upside is Thor's huge dealer network, which makes warranty work and parts far easier to access than with boutique brands.
