GMC 2500 HD specs

[Txforetravel]

Does anyone have options they chose for a 2020 GMC 2500 HD for pulling a 27-30’ AS? Duramax diesel but what else? Trying to spec one out for ordering.

As long as you pick a high enough trim level to get the ProGrade Trailering Package, you’ll have everything you really need.

As for creature features...I’m finding the MultiPro tailgate to be very useful, so do NOT delete that option. Standard on some trim levels and optional on others, the full coverage rubber floor mats are extraordinarily good at catching all water and mud and dirt. These are better than any aftermarket ones I’ve ever seen. If you like the idea of the invisible trailer camera view, make sure you get the right RPO that gives the camera inputs on the back bumper.

As for awesome-but-not-required...the heads up display is phenomenal, especially when navigating heavy traffic in strange locales.

The 3500HD is only a little bit more money, but gives you another 600lb. payload capability. But you’ll not need the additional payload for an airstream, as the 2500HD will have well beyond 3000lbs. in any configuration.

Be aware that the gooseneck/5th wheel prep will eat into payload a bit. So if you’re ordering and never plan on pulling that type of trailer, skip that option.

We just bought a 2020 Chevrolet Silverado Duramax LTZ. The higher level trim packages include most everything that you will want and need for towing. We added the Technology Package (all of the surround cameras). We also got the GM transparent trailer camera. We also got the LED roof marker lights just because we like them.

Thanks. That’s what I was looking for and a great tip on eliminating the gooseneck. Will never haul something like that.

Are you ordering a 2020 model or 2021? I thought the 2021s were not yet available.

2020. The 2021 model year is not out yet. The 2020s are slowly arriving after both GM and supplier shutdowns.

Just FYI our 2019 Chevy 2500 HD diesel Crew Cab 4wd Z71 has 2141# as the payload. We wanted 4 wd but the Z71 part probably wasn't necessary and took some payload away but it was on the lot and we liked everything else about it. So, make sure you still check the sticker if you're looking for that 3k payload in a 2500. We still have room to spare even with to 2 Hobie Kayaks and a Retrax Pro cover and Yakima HD Overahul racks Clam shelter grill etc. But we don't have kids or other full size adults going with us. We have an '05 Safari SS.

The entire GM HD truck line was redesigned for 2020 and they all have higher payload numbers. My very loaded Denali 2500 has a payload of 3000 plus pounds and I know of no option it doesn’t have.

Awesome! I kinda wondered if that was the case but just wanted to throw it out there. Guess we were just a year early.

As I firmly believe that there are no freebies in life, I’d guess that yours rides better.
Not that our new Denali rides badly, in fact it is getting better as I put some miles on it but... the free thing...

We have a 2020 GMC Denali 2500.

We also just received our new a new 2020 Classic 33 Fbt in July. We have used the new AS a few times over the last 60 days. The GMC pulls the Classic like nothing is there.

I had 2016 GMC Denali 2500 before getting this TV.

There is no comparing the 2 TV. The new 10 speed transmission and the new added torque with engine. The new added surround cameras are great too. they help a lot in backing and hitching up.

It is totally a WOW vehicle.

I ordered a 2020 GMC Sierra Denali 2500HD with the following options:

• Denali Ultimate Package
• 220 amp alternator
• Trailer tire pressure monitor system
• Polished exhaust tips
• Tri-fold tonneau cover
• California state emissions requirements

I'm towing a 2016 Classic 30RB (which by the way it tows very well), and it has a payload limit if 3,339 pounds.

You may have noticed that I didn't include the 6.6 liter Duramax option. Rather, I opted for the new 6.6 liter gasoline engine. I previously owned a 2019 Denali 2500HD w/ the Duramax engine, but wasn't a fan of the Duramax for a variety of reasons (not the least of which was the $10K price adder). I recognize that it's not an opinion shared by most 3/4 ton pickup truck owners, but I very much prefer the gas engine over Diesel. But, we typically tow our Airstream no more than a few hundred miles from home, and being in south Louisiana we don't live near any mountains. If we towed through the mountains I would probably opt for a Diesel, primarily because I'm sure the ability to brake with the engine would be very nice.

Finally, you may be wondering why I ordered California state emissions requirements (RPO Code YF5): I didn't really want the amber roof marker lights, but these are standard now on a 2020 GMC—that is unless you order it with the California state emissions requirements option. So, I ordered this option merely to delete the amber roof marker lights.

This article explains the reasoning behind California’s law... it is kind of interesting actually.

I have been wondering why California emissions and roof marker lights are incompatible on the order sheet. I'm really glad that California is really looking out for us with these common sense regulations! Thanks for the link to this "illuminating" story.

Like others here, 2 weeks ago purchased our new 2020 GMC and very much enjoying getting acquainted with latest features 3035 payload. Towing a 25Ft CCD SS. 5300/6300. Setting up new drop hitch so haven’t towed yet.

Great to hear others input/experience on this TV !

Increase payload may mean lighter /thinner components bedwalls?
Anyone else notice random low frequency vibration/thump 70-90hz From truck bed (pounding bass speaker like) When just driving unhitched / unloaded ? Kinda transfers into the rear of cab. Noticed 2 thin /loose square plastic caps back of cab wall facing bed that would let some noise in too. Can tap / light pound on front bed Wall to recreate vibrations. Any one else ?
Seems if some factory sound deadening material Was omitted.

Also if any recommends for a tonneau with front /back locking access and keeps the bed pockets open please advise.
(Had Fold-a-Cover on previous Denali and liked it but looking for an upgrade keeping bed pockets available).

[Duramax3oh]

Depending on personal preferences, but for me:
- Crew Cab, Standard Bed
- Duramax Diesel
- 4 Wheel Drive
- Integrated Trailer Brake Controller
- Trailer tire pressure monitoring system (note sure if GM or aftermarket is better)
- Roof Cab Lights/Markers (I love them and they're only $55 option)
- Multipro tailgate
- Sliding rear window (I have a weird affinity for them and dislike the solid rear window)
- Upgrade to 20" wheels (purely bc I like the look better)
- DELETE 5th wheel/gooseneck hitch
- DELETE running boards (see aftermarket)

After that I would look into:
- Camera/Technology packages. I could do fine w/o them but I've never used this in person so it could be amazing. If it saves one dent/ding/accident it's worth it!
- Is heads up display part of tech package?
- Sunroof if you're into it, I've learned I don't care about it anymore

Dealer and/or Aftermarket:
- Spray in bedliner
- All weather floor mats/liners front and rear
- Power fold/retracting running boards (like AMP Research)
- Bed rug carpeted bedliner (yes, over the spray in)
- Hard cover retractable and locking bed cover
- Possibly Ranch Hand front bumper/grill guard

*note I have the Silverado 1500 but would upgrade to 2500 tomorrow if my wife wouldn't kill me

We finally got Lucy's Invisible Trailer Camera installed and tested. This is a really significant option. no more guessing what is behind me in the highway. This camera can also be a standard rear view camera with the touch of a button.

Here are a couple of photographs of the truck screen with the Invisible Trailer camera in use.

Where did you run the camera cables and where are the cameras in the back of your AS?
