Default Gassy smelling exhaust

My 1998 heavy duty Dodge Ram 2500 Magnum V10 exhaust smells really gassy it has 106000 miles on it, it's had all of its regularly scheduled maintenance on engine transmission and differential throughout its lifetime was just looking for someone who might know what the problem is.
thanks Randy

it's running rich. o2 sensor? leaky injector? fuel pressure regulator? wrong/worn spark plugs?

is the check engine light on? any pending / codes?

No there's not a check engine light on and the spark plugs are in good shape and they're the right ones I just got this truck from my dad passing away I'm not sure about any codes pulling up I haven't had a chance to check that out yet I just noticed the exhaust smells real gassy

has it been sitting for awhile? if so take it out for a short cruise down the highway. sometimes stuff builds up and things get sticky when they sit. a good leg stretching helps before worrying too much.

Go to your local parts store, and have them plug in and pull any possible pending codes. Also check and see what the PCM thinks engine temp is. Wouldn't hurt to check fuel pressure as well, and see how fast it bleeds off when you turn off the engine.

Did you monitor fuel mileage on your way home? (no way I will refer to it as "economy"..... as there is NOTHING economical about the V-10. )

Your right it wasn't built for economy lol... yes we did and I was towing a U-Haul trailer with my 2007 GMC Sierra Classic Crew Cab on it and the Dodge was getting right around 9 miles per gallon and without towing anything it gets around 13 to 14 miles to a gallon
