This guide walks you through the critical steps of building out your van—starting with the most important upgrade: your roof rack.

Choose the Right Van for Your Build

Before you install anything, make sure you've chosen the right van for your needs. Here's a quick breakdown:

• Mercedes Sprinter: Most popular for van life; known for its durability, AWD options, and aftermarket support.

• Ford Transit: More affordable than Sprinter, widely available, and comes in AWD.

• Ram ProMaster: Front-wheel drive, square interior for easy builds, and most budget-friendly.

Each van has different roof dimensions and mounting systems, which makes choosing compatible gear especially important.

Install a Roof Rack (Start at the Top)

The roof rack is the backbone of your build. It’s where you mount solar panels, awnings, and more. Choosing a quality rack ensures you have the flexibility and strength needed for all future upgrades.

• Modular Design: Unaka roof racks are lightweight, low-profile, and built for DIY or professional installs.

• Solar-Ready: All racks are designed to support solar panel mounting.

• Accessory Friendly: Add ladders, awnings, and gear mounts without rework.

Add a Ladder for Safe Access

Next up: access. A rugged ladder gives you safe, easy access to your roof rack—for loading gear, cleaning panels, or catching a sunset.

• Direct Bolt-On: No drilling required; fits directly to Unaka roof racks.

• Built to Last: Powder-coated aluminum for all-season durability.

• Streamlined Look: Matches your rack for a clean, pro look.

Plan for Power with Solar Panels

Off-grid freedom starts with power, and our racks make it easy to get charged up. Every Unaka Gear Co. roof rack includes enough solar panel brackets to mount two 200W panels—right out of the box.

• Solar-Ready Design: Our racks are precision-built to maximize usable solar space—so you don't run into that frustrating issue where your panels are 1–2 inches too long for your rack. 
  

• Always Compare Dimensions: Always compare your solar panel dimensions to the rack dimensions to ensure proper fit.

• No Modifications Needed:

  Brackets are included—no need to fabricate or purchase anything extra.

• Need Help? Our team is happy to assist with panel layout and system planning.

Pro tip: Don’t settle for less solar. We’ve made it easy to go big from the start.

Stay Shaded with Awnings

Whether you're parked in the desert or under drizzle, an awning creates instant outdoor living space.

• Side-Mounted: Easily attaches to Unaka racks using Fiamma-compatible brackets.

• Quick Deployment: Crank out or electric options available.

• Protection: UV-blocking and waterproof for all-season use.

Expand with Rear Storage & Adventure Gear

Your van's rear door is one of the most underutilized yet high-potential spaces for storage and functionality. Unaka Gear Co. offers a range of innovative rear-mounted solutions designed to help you carry more and go further.

• Unaka Rear Ladder System: Not just for climbing—this modular system doubles as a mounting platform for additional gear.

• Spare Tire Carrier: Relocate your spare to the rear door and free up space underneath your van.

• Surf Poles: Strong, low-profile tubes designed to transport long, narrow gear like surfboards and stand up paddleboards.
