I would appreciate any assistance on this tow question. I PMd Gary (fifthwheelst), but just incase he is not available.......Just trying to do my homework...

Anyone towing a newer Landmark 365 (Newport is our choice) with a 2015 or 2016 GMC3500HD Duramax Denali DRW CC 4x4??
IF yes, can you share your CAT scale information or the actual vehicle specs from your manual or stickers? OR do I need to shop for a Dodge which seems to beat the Duramax tow ratings (but is not MY preferred tow vehicle).

We are thinking of buying a 2016 GMC3500HD Duramax Denali DRW CC 4x4 ON MONDAY.

Can you help me confirm a 2016 GMC3500HD Duramax Denali DRW CC 4x4 with 3:73 axle would be plenty of truck to pull a 2017 Landmark Newport.

I just assumed that I would be OK if I went DRW, but I would like your opinion, IF I may ask for it.

From the brochure, the Newport advertises GVWR 18,000lbs and dry weight of 15231lbs and hitch weight of 3210lbs. The brochure implies that dry weight does not include dishwasher, washer dryer and third A/C. Not sure how much weight that adds to delivered weight. This truck is rated for 22,600 lbs fifthwheel. So that looks like 22600-18000=4600 margin.

From 2016 GMCs tow capacity on line brochure I find GCVWR 30,500lbs GVWR for the truck of 13,025lbs The best curb weight I can find on the 3500HD is 6890lbs but it does not specifically say DRW. 5thwheelst has it at 7646lbs.

I have seen on this forum someone who said their Landmark had a 4000lb PW. The brochure says 3210 PW. The Newport will have the washer dryer up front and the bedroom with all the clothes in front of the wheels too.

My dealer is getting this truck from another dealer so I can not read the actual manual or stickers before Monday. OF course the special rebates they are offering expire on Monday 5-2-16.

IF GVWR is 13025, then I have 13025-6890 =6125 margin. 5thwheelst says 7646 still 5379 margin. I believe 7646 is closer, my 03GMC2500HD was 7700, loaded full of fuel with me in it on the CAT scale. I thought a DRW would be more than my SRW.

That should handle the advertised PW of 3210, or even the verbal 4000lb PW from the forum. (plus the wife and I and Fuel).

Rear Axle weight rating 7050 and rear axle curb weight 2962 = 4088 for hitch and PW.

It looks to me like this 2016 GMC3500HD Duramax Denali DRW CC 4x4 with 3:73 axle should be plenty of truck to pull a 2017 Landmark Newport safely and legally.

Do you agree? What should I ask the dealer or what other specs should I ask for validated before I would be comfortable making this purchase.

I am towing over my capacity currently, and the whole object of getting a DRW truck is to be legal.

IF I have to buy a Dodge to pull a Landmark Newport, then I have to come to terms with not being able to buy another Duramax. Please give me your opinion before I make a mistake.

Thanks in advance, Milt

Milt,

For planning purposes, you should assume that the pin weight will be at least 20% of the trailer GVWR, or 3,600. That's different from the pin weight spec which seems to be based on an empty trailer with no options. Your actual might end up higher than 3,600 depending on how loaded your basement ends up.

For reference, our 2011 Landmark with a GVWR of 16,000, fully loaded with options and gear, weighed in at 16,200 and a pin weight of 3,750 a few years ago. Ours has washer/dryer up front along with an Onan generator. The pin weight spec was 2,620.

When looking at the truck's payload spec, consider that the truck also has to carry the weight of the hitch, bed cover, bed liner, tools, firewood, extra fuel, pets, passengers and anything else you put in.

You'll want the payload spec from the label inside the door of the actual truck. Truck manufacturer websites and brochures often show the best possible numbers, rather than those for an actual configuration. For example, our 2014 RAM has a payload spec of 5,400 if I remember correctly. The ads say "up to 7,000". I think RAM's website lets you look up the specs by VIN# if I remember. Don't know about GMC.

I have a 2015 Chev3500HD LTZ CC DRW and had it weighted at the TN Rally. This is just for comparison purposes and I am not saying your truck would be the same, but here are my actual weight...This includes DW and I, B&W Companion hitch, tool box and full tank of full.

Without trailer:
R Front - 2500 R Rear - 2050
L Front - 2500 L Rear - 1950

GAWR Front - 5600 and GAWR Rear 9375

Hope this helps in your decision, I also looked at the Landmark's while at the rally and felt comfortable I had the truck to pull any of them safely and legally.

That truck will do just fine. If it is a 2WD it should have a GVWR of 31K....a 4WD GVWR drops 500#...well at least my 2013 does.

Bob we have the same 2013 truck, I was verifying the GCWR yesterday. The Crew Cab Long Box DRW Denali 4x4 - Max trailer weight is 22,300 lbs., GCWR is 30,500 lbs.

Yep Erica, being 4WD takes 500# off the GCVW. So far HL does not make a 5'er that weighs 22,300#. Well at least not yet.

I have heard that the 2017 D/A will be raising the HP and Torque ratings, so maybe the GCVW will go up.
