Looking for honest answer to see if my current tv 2004.5 325/600 cummins ram 3500 quad cab dually 6 sp man 3.73 rear end will tow safely a 44ft tri axle fifthwheel toyhauler, specifically a DRV JX450 which tops out at 24k. currently tow a 2012 keystone fuzion 360 40 ft tri axle toyhauler which tops out at 18k and the truck is stock and no probs towing/stopping with this unit. squats approx 2 inches hooked up so pin weight does not seem to be a problem? I will be adding an exhaust brake and airbags and possibly smarty jr if i go with the 6k heavier unit. I do not have the scratch for a 4th gen with aisin trany at this time so just trying to get the feel to see if i should be saving for it or keep the truck i got and spend $ on upgrades to tow the larger trailer. Current truck has 148K kilometers on it so in very good shape mech wise. thanks in advance for any feedback.

 

Should be no problem. If you go Smarty Jr it will be easier for sure.

 

Thanks for the input. I had a jr on a previous 2003 with 305h 555 tq and the 70 hoursepower towing setting woke it up good.

 

With what I know once you put the Smarty Jr on it plan on upgrading your clutch, the extra power from the tuner will cause the clutch to start slipping without the additional load of the camper. Just my two cents

 

Good Point.
