Fortunately the chocks were up to the task and it didn't roll away. Still, it's nerve racking to see your RV rolling away with nothing you can do about it even if it turns out to be just a couple inches.
What I'm wondering is if people sometimes drop their landing gear before opening the hitch jaws in order to reduce the chances of a roll-away. My thinking is that we should be able to lower the gear as long as we avoid pulling up on the hitch with the kingpin. Then once the gear is down open the hitch jaws then.
What's wrong with this method, if anything?
Best results with trailer chocked, landing gear down and slight reverse pressure on hitch before releasing. I like to put truck in reverse and ease against the chocks. This takes all the tension off the hitch jaws and they open easily. Never do anything without chocking trailer both sides fore and aft.
