Black Series Trim Levels Explained: Base vs Yellow Stone vs Rocky Mountain

You've decided on a Black Series — now you're staring at three trim choices and trying to work out whether the upgrade is worth it. Base, Yellow Stone, and Rocky Mountain aren't just badges; they change how far off-grid you can go, what you can run while you're out there, and how the trailer handles the rough stuff.

This guide breaks down what each trim is built for, what it adds, and how to pick the one that matches how you actually camp — without overpaying for capability you won't use or under-buying and wishing you hadn't. For the broader model-and-size decision, pair this with our how to choose an off-road travel trailer guide.

A note on specs and pricing: trim contents and prices change, and not every figure (like exact lithium capacity) is published. Where a number isn't officially listed, we say so rather than guess — always confirm current trim details and pricing on the model's product page or with Black Series before you buy.

The Three Trims at a Glance

	Base	Yellow Stone	Rocky Mountain
Built for	Capable off-grid camping at the best price	Maximum off-grid power & autonomy	The harshest terrain & weather
Power system	600W solar, 100Ah-based AGM bank, 2,000W pure sine inverter	Complete Victron-powered system, high-capacity lithium, advanced solar	Full off-grid power + reinforced systems
Headline capability	Runs your essentials off-grid	Run the whole trailer — including A/C — without hookups	Built to keep going where others stop
Suspension	Standard independent off-road suspension	Standard independent off-road suspension	Advanced air suspension
Best if you…	Camp off-grid but near resupply, want value	Boondock long, run big loads, want power independence	Tackle extreme trails, rough terrain, cold/heat

Exact lithium capacity, added solar wattage, and trim pricing aren't fully published per model — confirm with Black Series.

Base — Genuinely Capable, Best Value

Don't read "Base" as "basic." Every Black Series, including the Base trim, ships with a serious off-grid foundation:

• 600W of roof solar (four 150W panels)
• A 100Ah-based battery bank — 200Ah or 400Ah depending on the model
• A 2,000W pure sine wave inverter, plus 30-amp shore power
• Independent off-road suspension as standard

That's enough to run your fridge, lights, water, fans, and device charging comfortably off-grid for a typical weekend-to-week trip, especially with sun to recharge. (For how to stretch it further, see off-grid power for campers.)

Choose Base if: you camp off-grid but resupply every few days, you don't need to run air conditioning without hookups, and you'd rather put the savings toward the model and floor plan you want. You can also add capability later — our solar and lithium upgrade guide walks through it.

Yellow Stone — Maximum Off-Grid Power

Yellow Stone is the power-and-autonomy trim. It replaces the Base electrical system with a complete Victron-powered energy system, high-capacity lithium batteries, and an advanced solar setup — enough, per Black Series, to run the entire trailer, including the air conditioning, without relying on hookups.

That's a meaningful jump for anyone who:

• Boondocks for a week or more between resupply
• Wants to run air conditioning, an inverter microwave, or other big loads off-grid
• Camps in hot climates where A/C isn't optional
• Values the longer lifespan, lighter weight, and deeper usable capacity that lithium brings over AGM

The Victron ecosystem also brings better monitoring and charging control — you can actually see and manage your power.

Choose Yellow Stone if: off-grid power is the thing you don't want to compromise on. This is the trim for true power independence. (Exact lithium capacity and added solar aren't published — confirm with Black Series.)

Rocky Mountain — Built for the Extremes

Where Yellow Stone is about power, Rocky Mountain is about terrain and durability. It's positioned for "demanding off-road travel and extreme weather," adding:

• Advanced air suspension (in place of the standard independent setup) — for better control, adjustability, and ride over severe terrain
• Reinforced systems built to take a beating
• Full off-grid power

If your idea of camping involves genuinely rough, remote, high-clearance trails — or punishing heat and cold — Rocky Mountain is built to keep going where lesser setups get rattled, stuck, or overwhelmed.

Choose Rocky Mountain if: the trail to your campsite is as serious as the campsite itself, and you want the most capable suspension and most ruggedized build in the lineup. (Exact specs and pricing aren't published per model — confirm with Black Series.)

Which Trim Should You Pick?

Match the trim to your honest use case:

If you…	Best trim
Camp off-grid but resupply every few days, want the best value	Base
Want to run A/C and big loads off-grid for a week+	Yellow Stone
Tackle extreme terrain and weather, want the toughest suspension	Rocky Mountain
Want both max power and max ruggedness	Talk to Black Series about combining capability

A few honest rules of thumb:

• Buy up when it's hard to add later. Suspension (Rocky Mountain's air system) and a fully-integrated Victron/lithium system (Yellow Stone) are expensive and complex to retrofit. If you know you need them, get them from the factory.
• Base is the smart default if you camp within a few days of resupply and don't run A/C off-grid — and you can always add solar and lithium down the road.
• Don't pay for A/C-off-grid you won't use, and don't buy air suspension for gravel-road campgrounds. Match the trim to the terrain and trips you actually do.

Confirm Before You Buy

Because exact lithium capacities, added solar, and trim pricing aren't fully published, the last step is always a quick confirmation with Black Series on the specific model and trim you want — so you know exactly what you're getting and what it costs. Then sanity-check the whole purchase with our buyer's checklist, and if you're cross-shopping, our take on is Black Series worth it.

FAQ

What's the difference between Yellow Stone and Rocky Mountain trims?

They optimize for different things. Yellow Stone is the power trim — a complete Victron-powered system with high-capacity lithium and advanced solar, capable of running the whole trailer (including A/C) off-grid. Rocky Mountain is the terrain trim — it adds advanced air suspension and reinforced systems for extreme off-road travel and weather. Choose by whether power autonomy or rough-terrain capability matters most.

Is the Yellow Stone trim worth the upgrade?

If you boondock for a week or more, run air conditioning or other big loads off-grid, or camp in hot climates, yes — the lithium-and-Victron system delivers power independence the Base trim isn't built for, plus longer battery life. If you camp near resupply and don't need A/C without hookups, the Base trim may serve you well at a lower price.

What does the Base Black Series trim include?

The Base trim is already off-grid capable: 600W of roof solar (4×150W), a 100Ah-based AGM battery bank (200Ah or 400Ah by model), a 2,000W pure sine wave inverter, 30-amp shore power, and standard independent off-road suspension. It comfortably runs essentials off-grid; it just doesn't include the lithium/Victron system or air suspension of the higher trims.

Can I upgrade a Base trim to lithium later?

Yes — adding solar and lithium aftermarket is a common upgrade, though integrating a full Victron-style system isn't trivial and may affect warranty coverage, so confirm with the service team first. Our solar and lithium upgrade guide covers what's involved. If you already know you need that capability, buying Yellow Stone from the factory is usually cleaner.

How much do the higher trims cost?

Trim pricing isn't fully published per model and changes over time, so confirm current Yellow Stone and Rocky Mountain pricing directly with Black Series for the model you want. As a general guide, the lineup spans a wide range as you move up in model size and trim capability.
