The 3/4 trucks are heavier and have larger engines so they will get less mpg. Yes 3/4 trucks can carry more and tow more then a 1/2 ton. Unless you need to pull heavier trailers and or loads then a 1500 can handle there is no benefit to buying a more expensive truck that will get lower mpg.
Liston to this guy. More weight equals more gas. Stay with a half ton. I use them and they can easily pull a couple 48" and 21". I use an F-350 for bigger jobs like landscaping etc. Keep your truck you need a back up. Buy a used 1/2 ton with no more than 50,000 and you will be fine.
