This is right from the owner's manual:

. Do not tow a trailer during the first 800 km (500 mi) to prevent damage to the engine, axle, or other parts.
. Then during the first 800 km (500 mi) of trailer towing, do not drive over 80 km/h (50 mph) and do not make starts at full throttle.

I've warned DW that the first day towing is going to be looooong!

Those specs are saying that the option isn't available on those items: "Not available with..." then a list of stuff you can't get with the package. It's not worded that well, that's for sure.

I took delivery of a 2018 3500 Denali last Friday. The package you want is this:

Z6A

GOOSENECK / 5TH WHEEL PREP PACKAGE -- HITCH PLATFORM
TO ACCEPT GOOSENECK OR FIFTH WHEEL HITCH. Includes Hitch
platform with tray to accept ball and drilled box holes with caps installed,
box mounted 7-pin trailer harness (similar to (UY2) harness). (Requires
model T*35**3, (Z82) trailering equipment, (CGN) spray-on bedliner and
trailering mirrors (DF2), (DPN) or (DQS) . Not available with (UY2)
Trailering wiring provisions, (ZW9) pickup box delete, (9J4) rear bumper
delete, (VBR) rubber bed mat, LPO, (PDH) Interior Interior Protection Package,
(VBN) bed rug, LPO or any ship thru code.)

I haven't towed with it yet (I'm only up to 500 kms so still doing the non-towing break-in) but I did drop a new B&W Companion into the bed. It's a nice setup.

The ride is sweet, much nicer than the 2011 F-350 SRW. Hopefully the same holds true when towing.

Considering purchase of '18 3500 Duramax in a Denali pkg. The dealer cant tell me if the IBC will control my Titan EOH disk brakes on the trailer.

The IBC controls my Titan pump just fine, but you need an optional resistor or a spare electromagnet to fool the IBC self test.

I don't know about the disk brakes. The tow package I think is the receiver on the rear and it's plug. The under bed 5'th wheel prep will not fit your Pullrite. B&W & Curt make hitches for it, I have the B&W for mine.
