I had the same problem, it was hard to get an air hose to those and repositioning the cap did nothing. Your RV should have came with a tool, it is about 7 inches long with a socket on the end and a smiley face that you hold with your hand. This allows you to remove the hubcaps my unscrewing the lug nuts. The lugnuts that can be unscrewed are obvious, the rest are just for show.
That tool does not work very well and it will break under pressure, you need a 1 1/8" socket to get it off easily. You can gain access that way or cut the rim to give you the clearence you need.
If re positioning the cap does not work, read on.
You can also purchase valve stem extenders, which most RV places sell. These screw on to the existing stems and allows you to route the stem to make it easier to get a hold of. But, they are flexible, so it can be a little bit of pain sometimes getting air in to them. Get the solid ones if you go that route.
Lastly, I took mine down to a tire shop and had permanent extenders (basically long stems) put in (in the rear tires). It cost about $60, but these permenant extends are rigid and long so it is easy to add air to them. These just replace the stems that are already there.
A friend of mine said they have this problem in the city with ambulances and so forth. The only put in permanent long valve stems, because of the potential of the extenders to leak.

Agreed, their is some serious weight and danger in that idea (if you do not have the right jack and know what your doing). Take it to a tire place if you cannot resolve it on your own. The fix should be fairly inexpensive.
