Survey: How often do you chock your wheels?

Always when unhitched. Storage is flat so i just do one side but at camping site both sides get chocked. I know it's overkill but I use 12" 6x6 blocks. I needed them a few times on spots that were not level side to side and needed to stack 3 level blocks under the tires to get level side to side. If I had tried to use smaller plastic type chocks they would not have been tall enough on the downhill side. I've had the camper slide with the front jacks on wood before without chocks so now I chock every time.

Every time.

Always. Always. Always. Until the TT is hitched and locked to the TV, ready to tow away.

Always. When we first camped in our new to us fiver we did not chock the wheels and the when I pulled off the trailer rolled ever so slightly and landed on the bed of our truck. Never went without chocking wheels first ever again!

Always without fail!!!

Never on level ground.

I'm with JD. I always chock both wheels with those heavy rubber chicks prior to unhitching and then add X-chocks to both sides after unhitching. The X-chocks seem to reduce the bounce some. I have only the landing gears and rear leveling jacks. For an overnighter on fairly level ground I may not use chocks if the trailer stays hitched.

Allways

We not only put BAL chocks between the tires, but we also put plastic chocks behind each tire. And we have a bed saver in the bed of the truck attached to the hitch itself.

X-chocks between the wheels on both sides, wedge chocks both sides when not hooked to the truck.
I figure it's cheap insurance and doesn't take that much time.
