  • High-powered 10-speed intake and exhaust fan

Insulation - 3M Thinsulate

This inverter provides 1500W continuous power in pure sine wave form, so all of your electronics will be safely charged. It has a USB Port, triple AC receptacles, an over temperature indicator, overload protection and a low battery voltage warning/shutdown.

Battery Doctor Battery Isolator (AGM Batteries Only)

The Battery Doctor is a high-performance electronic isolator that allows you to charge two batteries from a single alternator. It keeps the starting battery isolated from your auxiliary battery, but charges both while the engine is running. You’ll never be stranded off-grid with the Battery Doctor. With a single push of the override/reset button, you can use the charge in your auxiliary battery to jump start your vehicle! A great entry-level priced product that performs reliably. Not for use with lithium batteries or alternators over 150 amps.

Sure Power Battery Separator (Any Style Battery)

The 1314-200 (unidirectional) and 1315-200 (bidirectional) are 200A battery separator modules with an integrated relay for 12V systems. The units monitor both the starting and auxiliary battery banks. If the starting battery is above the 13.2V connect threshold, the relay connects the two banks together so your alternator charges both the starting battery and the auxiliary battery. If the starting battery is below the 12.8V disconnect threshold the unit will disconnect the auxiliary battery and charge only the starting battery. This will preserve 100% of the starting battery capacity for engine cranking. Use the 1315-200 (bidirectional) if you want the option to reverse the current and jump start your engine with your auxiliary battery bank.

Mega Fuses & Bussman Fuse Holder

Even after installing a battery isolator, it’s very important to add fuses to protect your system. Mega fuses and Bussman mega fuse holders are a great way to ensure that an electrical short does not ruin your day. Make sure you use the appropriate amperage rating for your system.

Folding Shelf / Table Brackets

These brackets come in all different lengths and sizes. We often use the 12” reach on our builds. These brackets are strong, simple to install, and easy-to-use. They add a great custom touch to any build as a shelf or table extension.

Must-have Tools

Dicor Self Leveling Lap Sealant

Installing a vent fan or solar panels? Dicor is a must-use product. Don’t skimp on this step, use the best product on the market and keep your van dry on the inside.

Spray Contact Adhesives - 3M 80 and 3M 90

  • Fast-setting, high strength contact adhesive for attaching insulation or bonding rubber and vinyl inside your van

  • Features exceptional heat resistance for long-term durability

Dewalt Step Bit Set

Step bits are very useful because they can be used to drill a range of different sized holes with a single bit. They also help prevent you from drilling too far through interior body panels thereby denting and damaging the exterior panels of your van.
