Hi all, I got a 2003 Ram Hemi with 3.55 gears Quad cab and 4x4. I just bought a 30ft camper that wieghs 4567lbs dry. probably will be between 5200 and 5500lbs loaded. When I take O/D off the torque converter locks in 3rd instead of 5th. I only plan on going 60mph on the highway and this brings my rpms to 2500 rpms. I plan on going alot of places with this setup. Now my question is.......is this ok??? Will I be fine running at 2500 rpms for 16hrs straight???? I think I will be. I just wanna get some other opinions. Im thinking that 2500 rpms is accually right in the Hemi's powerband. The Hemi does like to rev!!! THANKS!!!
