The Fein Overlander Story

Available Today

According to our clients we build the World’s Best Land Rover Defenders…several people refer to a Helderburg Defender as a Work of Art or the Ultimate Adventure Vehicle so we had a Wild Thought! What if we were to offer the Ultimate Off The Grid Vehicle that is Perfect for Overlanding Adventures! Hence a fully customized 144″ High Top 4×4 Mercedes Benz Sprinter. This custom project took 4 months to complete and as you can expect from Helderburg is built to perfection. It’s the attention to details that makes this Off the Grid Adventure Vehicle unlike any others. There are so many small details that make this vehicle perfect for any adventure and with the low range 4×4 system you will be able to access backcountry locations to camp where there is no one else! The solar system will allow complete and total off the grid adventures. You have everything you need to be in comfort and cook gourmet meals. No expense was spared as you have come to expect with Helderburg. Mercedes Benz new car warranty applies.
