I wanted a safe jacking system for my large & heavy van. I did not feel comfortable getting underneath my van with a standard bottle jack, to do general service work or change a flat tyre. After a lot of research, I decided to purchase the Kojack system. You can purchase the Kojack as a kit, with various adaptors to lift the van in different situations which can happen if you need to change a tyre on the side of the road. My van has a jacking point, just to the rear of the wheel and the kit has an adaptor that fits snugly into the lifting point. That in turn is attached to the jack, making it a safe & effective lift. The best part is you don’t have to get underneath the van. The kit also has the “ball type” adaptor which I believe suits Jayco caravans. The entire kit comes in a nice carry bag and the quality is exceptional and will last a lifetime. It is permanently stored in my van and I would not leave home without it.
