I love the function of the chocks the only downside is they have no handle's. During a recent trip our camp site was on a slight incline. During the chocking process my camper rolled a few inches forward causing my thumb to be lodged between the chock and tire. After a medical diagnosis it was determined that my thumb was broken. I will be modifying my with a rope handle to be a safer alternative on inclines.
Excellent product, much stronger and better built than the competitors. Love how they interlock with the leveler blocks. Also made in the USA which is a huge plus!
