I went the homemade wood route. Work great. I have an old ratchet wrench and deep socket to use on them.
Using 1 on each side helps take out some of the wiggle in the TT as people walk around.
Plus when I am up on wood blocks to level out the TT, The plastic wedge blocks do not work unless you have long boards. I had a long board system once until it kicked up and allmost took out my dump valve.
Now I use the short ones.
The store bought metal ones I sure work well too. Good luck
