Amazing product, really helped my F250 get the gooseneck out of our 26ft living space. Before that, the truck was almost overloaded with a trailer attached, and driving was like sitting in a chair (okay, slightly exaggerating). With her help, I connect the air hose and lift the stern directly to the level. Driving is infinitely more stable. String, curves and brakes are much more reliable under load. I strongly recommend carrying any load on your back. The product is well made and the installation isn't difficult, but the instructions are really poor, which is why I gave it a one star rating. Too wordy and bad photos. Add more detailed photos with arrows and notes and a lot of installation steps and it will be perfect.
