The most important thing is to not stress the chassis with the straps. If I had the room inside the trailer, I would use a double stack stand, strapping the kart to that, and then strap the stand to the e-track, but I don’t, which is why my dad made his recommendation above. It’s all about making the trailer you’ve got to work best for you. But again, the key is to NOT stress the frame. You can bend it that way.
