Hello everybody. Going to Arizona on Tuesday to pick up my moms 2008 Frontier crew cab Nismo. She doesn't use it and I need it. Read a lot about the 4.0 and how strong it is. I have a 21 foot travel trailer. Dry weight 3400 lbs. Concerned about the Radiator issue. It's at the dealer now cause it has a small oil leak that they're fixing. So I called them and told them to replace the radiator. Rather be safe than sorry. Have to drive it back from Zona to Chicago next Friday. It's a good looking truck and am looking forward to driving it.
