Is there a difference, can the C5500 comfortably tow more than a C4500 can. Im looking to haul about 20k plus pounds on a goosneck/fifth wheel setup. I think that is slightly out of range for a C4500 maybe a C5500 could handle it however Im just not sure because its all the same motor. If anyone has any info that would be awesome.

I think both would be less that what I'd be comfortable pulling that much weight. I'd look at a true medium.
