Doing wheelies

[Coelacanth]

Ok, after some examination, my previous RV, the Itasca Suncruiser, had actual wheels with lug nuts. The Augusta has hub caps that simulate chrome wheels.
The valve stems are almost impossible to access and the edges to the opening are incredibly sharp.
So, the idea is to remove the hubcaps. In looking at various online postings and videos it seems that many of these have two nuts that must be removed in order to pry off the hubcaps. These nuts are marked to make them identifiable. But, in looking at my hubcaps I see no nuts that are so marked. So,...do my hubcaps simply pry off, as they would on a car?

That seems to be the problem when this subject comes up. This may help

Some people call them simulators when they are really hubcaps or wheel covers Like this


A real simulator bolts on the wheel and will not come off unless you loose a Lug nut
Like This

Or extender

So which one do you have??
