Focus on Your Adventure. When you’re in between power sources, you don’t want to be concerned about ice melting or game spoiling – and with an Engel Fridge/Freezer, you won’t have to be. Whether you’re out overnight and the truck’s not running or you’re underway and the genset’s idle, Engel’s tight seal and quality insulation keep in the cold so you can keep focused on your adventure. For nearly 50 years, adventure travelers have relied upon ENGEL to keep things cold when they’re on the move.
