Because nobody wants warm drinks on a rocky trail.

If you’ve ever opened your cooler after a bumpy off-road ride only to find your ice melted and your soda lukewarm, it’s time to level up. Installing a portable fridge in your Jeep Wrangler isn’t just a luxury — it’s a trail essential. Whether you’re overlanding through the mountains or tailgating by the beach, a fridge means cold drinks, fresh snacks, and zero stress.

Let’s break down exactly how to install one — step-by-step, with no dealership necessary.

⚙️ What You’ll Need

Before diving into wiring and mounting, gather your gear. You don’t need to be an electrical engineer — just have the right tools and a bit of patience.

🛠️ Tools & Parts

• Portable 12V fridge (ARB, Dometic, ICECO — pick your poison)
• Heavy-duty fridge slide (optional, but saves your back)
• 12V auxiliary power outlet or direct battery line
• Inline fuse or circuit breaker
• 8–10 gauge wire
• Crimp connectors
• Zip ties
• Drill + bits
• Ratchet set
• Your Jeep Wrangler, ready for adventure

🔌 Step-by-Step Installation Guide

1. Choose the Perfect Spot

Most Wrangler owners install the fridge in the cargo area. Fold the rear seats down or remove them if you need more space. Make sure there’s:

• Room for the lid to open
• Access to ventilation (fridges need airflow)
• A secure surface for bolting it down or strapping it in

Pro tip: If you often camp solo or pack light, consider mounting it behind the front passenger seat for easier access.

2. Power It Up

You have two solid options:

Option A: Use an Existing 12V Outlet

Fast and easy. Just plug it in. Downside? It might cut off power when the Jeep’s off — not ideal for overnight cooling.

Option B: Hardwire to the Battery

This is the preferred method for full-time cold.

Here’s how:

1. Run 8–10 gauge wire from the Jeep’s main battery through the firewall and back to the cargo area.
2. Use a fuse (usually 15A–20A depending on your fridge) within 12″ of the battery.
3. Connect the wire to a 12V socket or directly to the fridge if it supports hardwiring.
4. Make sure the ground wire is properly connected to the chassis or battery negative terminal.

You can also install a dual battery system if you’re going deep into the backcountry.

3. Secure the Fridge

Nobody wants 50 pounds of fridge flying around during a hill descent.

Mounting options:

• Bolt down a fridge slide for easy access (Dometic and ARB make great ones)
• Use ratchet straps or brackets to secure it to anchor points
• Install a cargo barrier to protect passengers

Want to go deluxe? Add a fridge slide-out drawer system with a built-in cutting board. Very #OverlandVibes.

4. Test Everything

Before loading it with cold brews:

• Check voltage at the fridge plug
• Confirm it cools down without issues
• Make sure it’s secure and won’t rattle (a trail run will tell you)

❄️ Fridge Tips for the Trail

• Pre-cool your fridge and items at home
• Use a fridge cover to improve efficiency
• Pair it with a solar panel if you’ll be off-grid for days
• Freeze water bottles to double as ice packs and hydration
