Secure Storage & Mounting Solutions for Van Power Systems – Must-Read Guide for Vanlifers!

 Anyone who's spent time in a van knows that in small spaces, design and layout matter tremendously. While many builders focus on battery capacity and solar panel specs, how you mount your power system is equally important. A well-designed power cabinet isn't just about protecting expensive components; it makes your van safer, more functional, and more reliable on the road.

Strategic Weight Placement

The positioning of heavy components like batteries significantly impacts how your van handles on the road. Placing them over or near the wheel wells offers several advantages, such as improved stability when navigating winding mountain roads, reduced vulnerability to crosswinds on highways, and better traction in challenging conditions like snow or mud. A lower center of gravity reduces rollover risk, while a more balanced weight distribution leads to predictable braking.

Your Power Cabinet Essentials

Every trustworthy builder will insist on proper mounting. Your van electrical cabinet must have the following:

  • Strong materials—either aluminum framing or, at minimum, ¾" Baltic birch plywood.

  • Secure connections through the floor or into wall structural members (not just sheet metal!).

  • Proper restraints to keep batteries from becoming projectiles during sudden stops.

Skyliner's aluminum cabinets, including custom electrical cabinets for Sprinter and Transit camper vans, provide exceptional strength without unnecessary weight. Their Infinity™ mounting brackets connect to factory points without requiring additional floor drilling. They've also incorporated dedicated ventilation zones for each component, addressing one of the most common problems in DIY van building electrical cabinets.

DIY Cabinet Construction: Critical Considerations

If you're building your own cabinet, several structural elements require special attention:

Materials and Reinforcement

Wood cabinets need substantial reinforcement:

  • Every corner should have metal brackets to prevent joint failure.

  • Use proper wood screws at every connection point, not just glue.

  • Add internal support beams where batteries will sit.

  • Reinforce any point bearing significant weight with metal strapping.

Wood naturally flexes under vibration. Without proper reinforcement, cabinets can literally shake themselves apart over months of driving. When in doubt, over-engineer your solution.

Mounting Requirements

The mounting approach depends on your cabinet material:

  • At least four mounting points are recommended for an aluminum power cabinet, 6-8 for wood.

  • For lateral stability, install rivnuts in the van walls and consider L-track.

  • Always use automotive grade-8 bolts with lock washers.

Wood concentrates stress at connection points, while aluminum distributes it much more evenly. While wood cabinets can still be a good solution, they need more attachment points and internal bracing if holding something heavy, like a full electrical system.

Accessibility When You Need It Most

Accessibility when troubleshooting matters tremendously with electrical systems. In an earlier layout, having to remove the driver's seat just to reset a fuse highlighted how critical good access design truly is. Make sure you can:

  • Visually check components, including the “hard reset” fix-all, without major disassembly.

  • Access fuses and breakers quickly (with clear labeling).

  • Check battery terminals with minimal effort.

  • Remove or replace components if necessary.

Skyliner's removable panels and smart layouts make these tasks much easier.

Thinking of an Adventure Van Build? Here's What I Learned the Hard Way

 If you're dreaming about building an adventure van and taking life on the road, you're not alone — I was in the same place a year ago. I wanted a rig that could handle backcountry dirt roads, haul my bikes, keep me warm at night, and still have space to cook a real meal. Here's what I’ve learned from actually doing it — and a few tips I wish I knew from the start. 1. Start With How You Travel Before buying gear or gutting a van, ask yourself: What does adventure mean to me? Off-roading in the Rockies? Remote surf trips? Park-hopping with your dog? Your travel style should shape everything — layout, gear storage, battery size, water tanks, etc. 2. Overbuild Your Power, Always Adventure means unpredictability. Weather changes, remote locations, no shore power — and that’s the point. That’s why I now swear by a solid electrical system. Solar + lithium + a reliable inverter is the holy trinity. I came across Skyliner Gear late in my build, and their Power Kit Cabinet wo...
