I used to have a silverado and got an 09 crew hemi. Love the engine and ride, it's powerful smooth and fun to drive. I get average 14-15 in town and 18-20 ish highway. Sometimes I drop lower if I'm having fun.
I like the looks of the interior on the fords better, but I think the Ram has it beat with storage and creative use of space.
I have had no problems with mechanical stuff or anything like that either.
So I would say it is a pretty solid truck to buy. Good luck
