Water?? Could it be that the water in the tanks settles to the intake when
the vehicle is not moving? Do you have a fuel/water separator?

Response from Sandra Price (not mechanical in any way, only sleep with my
mechanic): Since it runs better on reserve tank, your main tank could be
low on fuel. We know this because it has happened to us. Not many GMCers
trust their fuel gauge. We fill up after about 250 miles, no more than 300
miles.

Response from Bob Price (Sandra's mechanic): Check the fuel filters--(1)
inline, if it has an inline filter, and (2) in the carbureator. If it does
not have an inline filter, you should install one just before the electric
fuel pump so that trash cannot get into the electric fuel pump.

Sounds like you have a nice coach. Hope you get this challenge resolved.
