I vote, skip using chocks that sit on the ground or on blocks, and get you a set of BAL 'X' tire chocks that clamp between the tires of your TT. Highly recommend you get a pair of them (BAL used to sell a 2 pack of them, not sure if they still do?), so you can lock the tires on both sides.
Thats what we used for many years when we had an RV trailer, and they always worked great. Held the trailer in place very well, and were very easy to put on and take off. I only use blocks for leveling.
And, yes, the Camco blocks you have are a good choice, you will like them. I have two sets of them (total of 20), and still use them pretty regularly.
