I have an 83 dodge d150 727 auto 3.55 gears 318 4 BBL carter, I've heard many people talk about rv cams and how it got them fuel mileage gains and power, first I'm wandering what an RV cam is, if there's a certain brand or if it just stands for something, any other fuel mileage tips would be appreciated.

 

a rv cam has a couple different names. can also go by the name towing cam.
