Upon returning from our trip about 1 1/2 weeks ago I parked the coach in our
yard and I walk down the passenger side
to get to my car every day.
Both my wife and I can smell gasoline. We have traced the strong order of
gas beginning behind the front passenger side tire all the way down to the
end of the coach only on passenger side, stronger by the side entrance door
and near the rear wheels. No odor what so ever under the front end or any
where all the way down the drivers side.
As I have stated to most of you before, I have a sight problem, especially
in darker areas such as under the coach. So I am trying to explain to my
wife what to look for but could not find a schematic for gas tank and fuel
lines.
I have to be home during a bright sunny day to see anything and even then
may still be too dark under there, and am at work until almost dark every
day. I am going to take the dog house off and see if anything obvious is
around the carburetor, but if anyone can shed some light or this sounds
familiar to anyone, please let me know.
I will not try and start the coach until I figure out the mystery.
Thanks
Ray Lucas

Ray,
Most likely...
The evaporative cannister for the fuel tank venting is located near the rear of the passenger front tire. If the gas tanks are filled very full AND the vent float valve shut off (located in the rear driver side wheel well) is not working -- you can experience overflow into the cannister. The cannister has a filter bottom so liquid fuel will pour out. If your coach is sitting nose high it may also be that the fuel spilled to the rear along that side.
Possible but somewhat less likely...
The original mechanical fuel pump is also on the passengers side but at the front corner of the engine. A leak here usually stays in that area -- but it could also run back along the frame.
Fuel spill smells can linger for quite a while -- and a small amount can be rather strong.
Others will have additional thoughts.

When I initially drove "The Money Pit" home to OKC
from the San Antonio, TX area last March, the smell
of raw gasoline was pretty potent. Later, I found that
the fuel line between fuel pump and carb was leaking
VERY badly. I had the same situation when I first
filled (probably over-filled) the fuel tanks.

Sir: If you raise the inside hood you can see with a good light the fuel lines on the engine & pump and the filter canister and lines under the pass seat towards the rear. You can see more if you remove the inner wheel liner on the pass side. This takes about 3 minutes with socket or nut driver. Remove the screws around the wheel and one in the top middle and roll the liner toward you and it comes right out. It is plastic and flexible.
Here are the manuals if you need them.

Ray, after purchasing my Royale I had much the same condition as you
describe. What I found was that the evaporative emission vent lines that go
from the tanks to the fuel/vapor separator in the drivers side wheel well
and from there to the charcoal cannister located in the front passenger side
wheel well located behind the inner fender, were severely deteriorated to
the point of crumbling in your hand. When the tanks are quite full, liquid
fuel can and does go through those lines which lay over top of the tanks.
The fuel can spread over the top of the tanks and drip off the frame near
the entrance door. The fix is to drop the tanks and replace every flexible
hose there with high quality fuel injection hoses. The temporary fix is to
lower the level of fuel in the tanks until you can drop the tanks and
replace the hoses. Meanwhile, don't smoke or produce any sparks in the area.

Ray - where are you located? There may be someone in your area familiar with this problem who could help you investigate.
I vote for stuck fuel vapor separator, or deteriorated vent lines.
