My 16K Reese slider has a tendency the 'thunk' (starting to love that word!) but only when I am traveling slowly; through a town with lots of stop 'n goes, for eg.
I am running a Curt Discovery controller set at 3.0 and 3.0 for hiway. If I back the secondary off to 1.0 or so at the first stop, there is no problem and the thunk is gone and stops are smooth. I repeated this several times in a WalMart lot and now do it habitually as we encounter the speed zones coming into a town.
Although this works for the 'thunk' when braking, I like the idea of shims better.
dunnnc, did you come up with your shim thickness through trial and error, or did you discover a way to measure the gap beforehand???
