I was thinking of trying one of those tri-levelers for my TT instead of wood blocks have anyone used them? Also the plastic chocks keep coming loose from my tires and the camper shakes driving Miss Gail crazy. How about those ratchet type wheel chocks that go between the tires? I have also seen a type that is like those plastic chocks but are metal and ratchet at the bottom of your tires and keep them tight. Am I a half a bubble off or am I making this harder than necessary. I have 2013 Springdale 33'-6" long. Any help will be appreciated. Thanks
