C4500 vs a 2015 HD2500

The new towing specs for the HD2500 Duramax trucks state that I can safely tow a fifth wheel weighing 17.9K.
As we all know towing is not the problem, stopping and downhill control is more of an issue.
I have absolutely no issue with my Top Kick C4500 with pulling or stopping but would someday like a newer Truck and something with 4WD.
Am I going to be disappointed with a SRW Truck even thought GM has upped the towing specs.
I think the breaking, grade control and exhaust break are all great new additions to this 2015 line of trucks but I wanted to get some advice from some of you out there towing with the new Trucks

Thanks,

Mark

Probably the only way you are going to know is if you can borrow one and compare the
two towing your rig.

I've pulled that much with an 05 2500HD, that being said I would think that is a lot of weight behind a 2500! I'd look more for a 3500 SRW.

2500 lacks the suspension for that weight in stock form.

I would put airbags on to support the bed weight

What I didn't add earlier is my hauling was mostly back roads and speeds under 50. I wouldn't try it on the freeway.

My trailer is only 12k lbs, but the '13 does a great job compared to the '03 it replaced. Went over Monarch Pass this summer and hardly touched the service brakes, the exhaust brake and manual mode allowed me to control decent very well. On the last few hundred miles coming home, the trailer brakes stopped working, but it wasn't a big deal.

Get the new truck but make it a 3500HD instead and if your not happy with the stopping power, then add disc brakes to the trailer.

I think the 2500 lacks the two extra wheels for that weight as well. I would want the stability of a DRW truck if I was towing that kind of weight often.

Also the 2500HD has less springs than the 3500HD does.

I had a 2004 GMC 2500HD sense new and I have pulled 36K with her a few times.
Stopping was not a problem with good working trailer brakes... with no trailer brakes there is NO way that truck would even slow that kind of weight down.
If you are towing muck more then 3500 pounds you need trailer brakes!
