I finally got a hold of Thor Tech Support and they verified for me that the simulaters on my 2017 Thor Vegas 25.4 are the old style pry off and snap on type. They suggested getting the broadest flat blade screw driver I could find and wrap the blade with a cloth. The carefully prying the simulater from the wheel rim. I seem to remember something called a tire spoon that was also handy at removing hubcaps. I will try to locate one of those to add to my Motorhome tool set. Ray
