Having been a truck owner for the past 20 years. Ram by far is better than Chevy and Ford...GMC is king...don't know what ram you had...my 5.7 v8 long horn drives great and had no problems and 5 years now.The ram is a piece of shit.
The v6 is underpowered and has reliability issues.
The 5.7 v8 has lifter & roller problems as well as exhaust manifolds made out of paper mache ($2.5-3k repair)
The diesel is a grenade waiting to explode
Go with Lexus or another pickup brand, such as the Ford f150 with the 5.0 v8
