Gas smell coming from exhaust

I recently purchased a 1986 Travel Master and noticed a faint smell of gasoline in the cab while driving the other day. Once I was home I checked to make sure the gas cap was good and for any noticeable leaks and didn't see any, but I noticed a pretty strong smell of gas coming out of the exhaust pipe. What could be causing this? Does it require immediate attention or am I okay to drive?

sounds like your mixture is way off.  Do you have EFI?  If you are carbuerated, I could see how that might happen.  Not really up on the older ones, but I was just looking at an EFI the other day and noted it had an O2 sensor and a mass air flow sensor.   Raw gas is rough on catalytic converters (kind of doubt you have one).
