Whether you’re building out a new adventure van or looking to upgrade your current rig, exterior accessories can dramatically improve your Class B van’s capability, storage, safety, and overall look. From suspension upgrades to ladders and roof racks, these add-ons help transform a simple van into a fully equipped, go-anywhere adventure vehicle.
This guide covers the most popular exterior accessories for Class B vans, including Mercedes Sprinters, Ford Transits, and Ram ProMasters. Consider this your starting point—each category can be expanded into its own detailed article in the future.
Why Upgrade the Exterior of Your Class B Van?
Stock vans are designed for commercial use, not off-grid living or extended travel. Exterior upgrades can:
- Increase cargo capacity
- Improve off-road performance
- Make your van more functional
- Enhance safety and durability
- Support bikes, boards, kayaks, tools, and gear
- Personalize your van’s style
Whether you’re planning a full build or slowly upgrading as you go, these accessories make a huge difference in usability.
Most Popular Exterior Accessories for Class B Vans
1. Aftermarket Front & Rear Bumpers
Upgrading bumpers is one of the most common modifications for Class B owners who travel off pavement or want extra protection.
Why upgrade your bumpers?
- Better protection from impacts
- Ability to mount lights, winches, or recovery gear
- Improved approach and departure angles
- Tougher, more rugged appearance
Common features:
- Bull bars
- Integrated winches
- High-mount LED light bars
- Recovery points
- Heavy-duty steel or aluminum construction
Brands commonly used in Class B builds include Owl Vans, Agile Offroad, Van Compass, Backwoods Adventure Mods, Aluminess, and others.
2. Suspension Upgrades
Most Class B vans carry far more weight than a standard cargo van, especially when loaded with water, batteries, and gear. This can cause sagging, poor handling, and excessive body roll.
Popular suspension upgrades include:
- Upgraded shocks and struts
- Rear leaf spring packs or helper springs
- Progressive or heavy-duty coil springs
- Sway bars for better stability
- Full suspension kits for lifted or off-road setups
Benefits:
- Improved ride comfort
- Better handling in wind and on highways
- Increased ground clearance
- Reduced sag when fully loaded
Suspension upgrades are especially beneficial for Sprinter vans, which often become top-heavy after conversion.
3. Wheels and All-Terrain Tires
Swapping out the factory wheels and tires is one of the easiest upgrades—and one of the most impactful for performance and style.
Reasons to upgrade wheels & tires:
- Better off-road traction
- Improved durability
- Increased load capacity
- More aggressive look
- Better performance on snow, sand, and gravel
Common tire choices:
- All-terrain (A/T) tires
- All-weather snow-rated tires
- LT (Light Truck) rated tires with higher load capacity
A/T tires from BFGoodrich, Falken, Toyo, and Michelin are extremely popular among Class B owners.
4. Roof Racks
Roof racks unlock a huge amount of storage potential—especially valuable on smaller vans.
What you can mount on a roof rack:
- Solar panels
- Extra cargo boxes
- Sporting gear (surfboards, skis, kayaks)
- Light bars
- Roof-mounted AC units
- Tents (depending on van roof type)
Why roof racks matter:
- Keep bulky items out of the interior
- Allow for future expansion (lights, awnings, gear)
- Provide a stronger mounting surface than factory rails
Roof racks are available in full-length deck-style platforms or lightweight modular designs.
5. Exterior Storage Racks & Carriers
Rear-mounted storage is incredibly popular in the Class B community because it expands space without cluttering the interior.
Common storage rack options:
- Cargo boxes for tools, leveling blocks, hoses, etc.
- Swing-out carriers for gear or bikes
- Spare tire carriers (essential for van builds that delete the under-van spare)
- Fuel or water can carriers
- Box + ladder combos
Brands like Owl Vans and Aluminess dominate this category with modular, lightweight aluminum systems.
6. Rear & Side Ladders
Ladders make it easy to access your roof rack for cleaning solar panels, loading boards, or performing maintenance.
Ladder benefits:
- Safe access to the roof
- Great spot to mount accessories (shovel, recovery boards)
- Adds rugged, adventure-ready appearance
Many ladders are “bolt-on” for Sprinter, Transit, and ProMaster vans and can be mounted on either side or the rear doors.
7. Awnings
Awnings create much-needed shade and outdoor living space, especially in hot climates.
Popular awning types:
- Manual pull-out awnings
- Motorized awnings
- 270-degree wrap-around awnings (common on off-road vans)
Why awnings are useful:
- Expand your living area
- Provide shade for cooking
- Protect doors from rain
- Ideal for campsites and beaches
Fiamma, Thule, and Alu-Cab are popular options.
8. Lighting Upgrades
Exterior lighting improves safety and expands what you can do after dark.
Popular lighting additions:
- Light bars
- Fog lights
- Underbody rock lights
- Rear work lights
- Side-scene lights
These are especially helpful for boondocking, off-road travel, and nighttime campsite setup.
9. Window Upgrades
Adding or replacing windows enhances both visibility and comfort.
Types of upgrades:
- Ventilation windows
- Slider windows
- Awning-style windows
- Insulated privacy windows
Good airflow and natural light significantly improve the van-life experience.
10. Skid Plates & Undercarriage Protection
If you plan to travel off pavement, underbody protection is a smart investment.
Protects:
- Fuel tank
- Transmission
- Engine oil pan
- Differential
- Sensitive wiring
Skid plates help prevent expensive damage on rocky or rutted trails.
Which Exterior Upgrades Should You Start With?
If you’re new to Class B life, the most important beginner-friendly upgrades are:
- All-terrain tires
- Suspension upgrades
- Rear storage box or spare tire carrier
- Roof rack with basic accessories
- Ladder for roof access
These provide the best balance of practicality, safety, and long-term value.
