    Question Roof rack for 3D JK for mounting roof top tent

    I am trying to find roof rack for a short JK for installation the roof top tent like ARB SIMPSON SERIES III.
    But there is one limitation:a small design is preferred, so that it can be sent from the US at a low cost.

    I think about Rhino Racks backbone system with 4 mounting points.

    As I know the maximum static load is 240 kg for short JK and 360 for JKU.
    But the question is: is it strong enough for the tent + 2 two adults?

    I'm sure it's strong enough. I would change to 1" bolts though.

    Could you be a little more serious?

    According to my calculations: the tent weighs 50 kg, two people (I and my wife) - 160 kg. Total is 210 kg. This is close to the maximum 240kg.
    But what if two people will be I and my brother - about 220 kg total? It is 30 kg more than maximum. Not a universal solution

    I think you'll be fine. With any of this stuff, it can probably hold 2x what they say. It's called a factor of safety. It's designed to hold anywhere from 1.5-3x what they say depending on what would happen if it were to break. The worse the damage would be, the higher the factor of safety.

“wayoflife” is a moniker that I’ve been using for 20 years now and I chose it because I think it does a great job of explaining, in simple terms, the passion I have for Jeeps and the Jeep way of life. This is a lifestyle that transcends age, gender and race as the only thing you need to be a part of it is a love for the outdoors, a desire to explore, a yearning to take on a challenge and a will to conquer it. Over the years, Cindy and I have attempted to capture the essence of this lifestyle through photographs and videos and share it with others around the world. And, this is how WAYALIFE was born.
