When we came back from our last trip it was raining when we packed up and was still raining when we got home and backed the TT in the slightly sloped to the road driveway. We put one of those orange plastic chocks under a tire on each side of the TT and then placed a 6x6 under the tongue and began extending the power jack. When the TT released from the ball it slid towards the truck a tiny bit.Would this possibly be from all the wood, the chocks and driveway being wet? Is the TT coming sliding forward a hair acceptable?I'm assuming that since we installed the chocks and then were lifting the front of the TT up that the tires went back away from the chocks ever so slightly since the front of the TT was being raised.Should we install the chocks and then drive up them a bit next time before trying to unhitch? Any other suggestions?

Moving a little is not big deal. There's no way you can jamb the chock tight enough under the wheel that it won't move at all. If you try to pull up into the chocks you will most likely just a bit too far and put tension on the hitch. Then, when you unhook the trailer will roll back just a hair.Don't worry about it. Sometimes when I get in a hurry with my equipment or cargo trailer I don't chock them well enough. I've had it move several inches many times. It stops when it hits the chocks.

Plastic chocks on cement with a slope. I would imagine it's allowing some slippage,especially if wet. Also possible that the electric tongue jack may be slipping on the wet wood.I went to our local tractor supply yesterday and bought some heavy duty rubber chocks for parking our class C in our sloping (towards house) driveway. You might want to look into something like that. Might aid in slipping.

Take a rubber mallet to the plastic chocks is another idea.

You could get a rubber mallet and hammer your chocks snug on either side of the tt tires. Or you could get some metal x-chocks for tandem axle that will secure your rv.

get the rubber type chocks, they will give you much more confidence that they will stay put. Moving the jack up and down will cause the trailer to move some so having chocks in which you have confidence is important. FYI, I got mine from Harbour Freight
