Just wondering what annoyances I’m going to encounter with the new High Country? I went from a 2019 HC to a 2021 Denali and was greeted with bonus safety features, such as a warning on the DIC every time I set my cruise control because I have my adaptive cruise disabled. I wonder what other surprises I’m going to find on the “refreshed” model. I heard that you can not put the vehicle in drive without buckling the seat belt.. Any other wonderful little things like that?

Anyone compared the three in person? I see the center touchscreen area is different on the Chrv, like the lower tier GMC’s. is the Denali/AT4 actually nicer, or just different? also, does the AT4 have the configurable instrument panel like the Denali does? From what i’ve gathered the Chev does not. I have not had the opportunity to sit in any of these trucks yet to form my own conclusion, hoping someone here has.

Thanks! The dry weight of the trailer is actually slightly under 9,000lbs but the front bedroom/bathroom and mid kitchen configuration makes it very tongue heavy. It’s a Blackstone 280RLSB. It’s a 35’ trailer with 31’ interior floor space. I’ve previously owned a Blackstone 280RKSB which is identical size but had the kitchen in the rear and it was tongue heavy too but not as bad, as the rear kitchen helped to counter it a little better. i would never select this configuration, I don’t dry tongue weights pushing 1000+ lbs unless it’s on a toyhauler but getting a great deal on a used but like new 2016 model so taking the bad with the good.

I’m buying a 35’ RV that has a 1370lb dry tongue weight. That’s without propane, batteries, water (80gallon tank) and personal belongings. I could see tongue weight creeping up near 2000lbs. What is the stock hitch rated for?

4 turns was 1”, still get slight rubbing but I can deal with it. I actually had to trim the front air dam a little while it wasn’t necessary at stock height. Still have 3/4” rake. Ride quality was no noticeable change, I’ll be getting an alignment done soon now.

Not looking for 2-4” of lift and want to maintain a slight rake without adding rear blocks, just want to dial it up enough to eliminate tire rub with my 295/65-20’s on 0 offset wheels. Hoping 1” would do it. Has anyone done this, did ride quality suffer? Any issues with upper control arms / CV angles? How many turns was it?

I just mounted 295/65-20 Toyo AT3’s on 20x9 0 offset BMF REPR’s, stock suspension height. I had to tie the front inner fender liners forwards, and still have some pretty serious rubbing at the back on my stainless mudflaps. Not sure what to do about them. They’re so thin that even if I remove them I will have rubbing on the hard plastic that they are mounted to. I didn’t want to have to either do a levelling kit or find some wheels that I actually like that have a positive offset.

Speedometer seems deadly accurate now with the 295/65-20’s, go figure. I never checked it with the stock tires.

Are dealers able to do this? Putting 295/65-20’s on a 2020 3500SRW and would like to be able to run the rears lower than the 62psi that triggers the low air warning.

Despite what I read here I decided to try it and mine appears to be effective at -12 to -15 the last couple of days.

On my recent 1500’s and the wife’s Yukon/Tahoe the block heater didn’t do anything until ambient temp was down to around -20 C. Is it like this for the duramax too? Haven’t been plugging mine in this winter as it’s been a warm one and temps haven’t been anywhere near -20.

You won’t notice the lack of headroom that I did, I’m 6’5. If your inseam is anywhere close to mine though (34”) you’ll notice the dashboard extends out to almost hit your right knee, even with the seat all the way back. the difference in interior space is huge, I was shocked.

Still has way less legroom up front. The seat doesn’t go back any farther than the crew cab. I’m 6’5 with not exceptionally long legs, 34” inseam, and my right knee is literally a short leg hair away from touching the dashboard in the Ram. I expect if I got in an accident driving one my right knee would be toast.

I was very close to buying a new Ram. They’re a beautiful truck. Unfortunately there is no room in them if you’re tall, my right knee was against the dashboard and my head was brushing the headliner, with the seat all the way down/back. I couldn’t believe it. I was ready to buy it as I was really smitten with the truck but that was a deal breaker for me. I then drove the new GMC and despite finding it a little visually unappealing, I really liked how it drove compared to the Ram. The Ram felt really stiff and the engine felt laggy in comparison. So much more leg, head and shoulder room in both the front and rear seats. Only complaints are the spongy feeling brakes and the kind of awkward looks. I like the interior, it may look a little underwhelming but everything is well laid out and pleasant to use. One more thing the Ram really lacks is bed access. GM’s bumper steps really are great. Better than Ford’s tailgate step, and Ram still has nothing. As for the Multipro tailgate, I could not care less about it. I have it but don’t need it or use it.

Around 17-18 mostly highway with some city mixed in.

I’ve gone about 2500 miles and my gauge says half full, no towing.

First tank I got 18.4 hand calculated, 60% highway 40% city, 634 miles between fills. DIC said 19.4.

Those are great numbers. What spec is your truck? Stock tires?

How much did the 295’s effect fuel mileage and odometer?

I have a 2019 1500, have had several 1500’s before this one 2014 and onward, and a Lifted 2015 3500 with 35x12.5” tires on 20’s. Brakes were good on all of them. this week I’ve test driven two separate 2020 3500 SRW Denali’s, one CCLB and one CCSB. Brakes are seemingly very weak on both and require a lot of pedal effort. I thought there was something wrong with the first one until I drove the second one.

I test drove a CCLB SRW Denali today, got 22mpg on a 30 mile loop, speeds mostly 50-65mph country roads and highway. My 2019 1500 High Country with 6.2 gas I pre-ran the same loop, same conditions and driving habits and got 25mpg. Start and finishing points the same, blah blah blah, it was as controlled of a test as one can do. My lifetime average with the 1500 is 19mpg hand calculated, I typically get 15-16 around town and 21 highway And DIC is deadly accurate. That being said I put 91 octane in the 6.2 which costs 25% more than diesel around here at the moment. I was hoping for slightly better with the duramax but my expectations may have been unrealistic. I signed the deal, trading it in.

Crew cab standard bed 4x4 high country, Z71 3.23 rear end, 91 octane

The 6.2 is better on fuel than the 5.3, I’ve owneda 2014, 2017 and 2019 6.2’s and a 2018 5.3. Out of these 4 trucks the 5.3 was the worst on fuel. The best was the 2017 6.2 /8spd. hand calculated on my 2019 is consistently within a couple tenths of what the DIC reports. here’s my log of my 2019, mix of city/highway. 4x4 High Country standard bed Z71. 6.2/10spd, always running 91 octane. My 18 double cab 4x4 elevation edition 5.3 was around 10% thirstier.

Does this engine require premium gas, or is it recommended? Or does it run fine on 87 octane like the 5.3? Thinking about trading the wife's 16 Yukon in on a new RST with the 2.7, as most of her driving is around town and the 2.7 should be a noticeable improvement in MPG's. If it requires 91+ octane, we'll likely stick with the 5.3.

2017 Silverado 4x4 Cc 6.5 box, LTZ Z71 with 6.2, 8spd and 3.42’s completely stock, lifetime average 20.25mpg hand calc, best tank was 22.2. Mostly highway. Very pleased so far. DIC consistently reads 5% on the generous side.
