Probably not towing the weight some are , my fifth wheel is only 15,500 GVWR , around 14,500 loaded these days . But the Cummins gets the job done nicely up ,and down the grades here in the mountain west .
An EB is nice to have for a 14000 lb trailer but not absolutely necessary for most highway grades. I remember descending a very long 8% grade with 14000 lbs in tow in the days before the factory EBs were available. My 03 Duramax at that time held the trailer back with zero brake applications at 5000 rpm in 1st gear. I used a 2011 Powerstroke on that same hill pulling the same 14000 lb trailer. The 2011 Powerstroke had a poor EB but it was good enough to comfortably descend the mountain in 2 nd gear at about 3500 rpm without any brake applications.
I have towed those same grades with the same weight with a 99 Superduty 7.3 Powerstroke with no EB, and no it was not a pleasant experience, going up or down . There is one coming down into Virgina City , MT that 14K or 20K is sure nice to have a decent EB . You don't see many runaway ramps , that hill has one , its not for the faint of heart towing heavy ,and just a two lane road . Sure I got by without EB as many did in years past, but I was careful , low speeds ,and gears . Those days are gone now , I let that Ram do it's thing .
Wow 5000 RPM with a diesel , I'm sure that 6.7 Cummins would have pistons thru the block at that RPM . :B
