I have a 30' Jayco Jay flight. This is our first travel trailer. I recently leveled our trailer and when disconnected from my truck it rolled back about 2" and partially crushed my plastic wheel choc...
X-chocks are for stopping the wiggle but they still are not as effective at preventing the trailer from rolling down a hill as actual wheel chocks. Learn from my mistake. Its only luck that myself or one of my children were not in the way when the trailer rolled off the tongue blocks and crashed on the ground. I cannot stress this enough. Just because it hasn't happened to you does not mean it won't. A mistake I will not make again.
