  1. LOVE my'15!!! 24mpg

    The fuelmileage is off by less than 10%. I checked my odometer with the Garman GPS it was off 12 miles in 2000. Also my speedometer is dead on at every radar trap I drive through and my GPS Yes it's a little high bet I hand calculate every tank and it's never more than 2 mpg high Also IF the big tire size slowed my odometer it would make my mileage look worse than it actually is so you have that backwards. but like I said my odometer and speedometer are both good. So......no dice Ps I'm not a retard and a used talk to text when I drive so sorry For the jiberish Sent from my iPhone using Tapatalk
  2. LOVE my'15!!! 24mpg

    I honestly can't imagine being any happier this truck after one year of ownership! Thanks gmc! Doing 78- 80mph across Iowa 550hp ppei, air dog g2 and down pipe back age. Also HEAVY 305/50-20 ha kooks. Sent from my iPhone using Tapatalk
  3. Under seat storage?

    I have the husky. They're all way over priced, but it does the job. Fit is perfect on my 2015hd crew Sent from my iPhone using Tapatalk

    Exactly... It's good for it to work a little. The first 150 was empty the next 150 was 60mph the next 300 was 70mph hills and it didn't break a sweat. Coasting down. Hill easing up hill. Cool ambient temps, consistent highway cooling. These motors are run in at the factory too. I went really easy on it. I'm a mechanic and IMO it was the perfect break in. Enough heat to set the rings without excessive heat which causes dreaded glazing. The rules the manual lays out have to be as close to dummy proof as possible. If you understand what's good and bad during break in you can get away with doing a lot of things. Sent from my iPhone using Tapatalk

    Torsion bars are adjusted by cranking a bolt that pushes on the torsion bar key. 1/2 ton trucks have coil springs on post 2007 trucks. 2500/3500 use torsion bars which are adjustable. Sent from my iPhone using Tapatalk
  7. Thought I'd share. I did not level or do any suspension mods. I DID however crank the front bars up just for looks. I like Rake but it had a LOT of rake. I hate the Nose up in the air boner look that they call "level". IMO the body of the truck is not designed to look right with the fenders are level. It's designed with a lot of rake in mind. So level looks like nose way up in the air.... Anyway.... I went 4 turns on the front T-bar bolts. Which was between .75" and 1" up at the fender. I did that before switching tires and I have to admit the ride suffered. I would have gone back down if I didn't switch tires. We will see how it goes with more rubber. I think the look is just right. Narly enough without to much noise or chop. I will say that adding 33% more rubber weight to each corner (51lbs vs 73lbs) is a bit too much for the stock shocks. Maybe I should have gone for the z71? I may upgrade the shocks sometime. It's not bad just take a little while to settle after a bump. Otherwise I'm pretty happy with them. Yes they probably cost me 1-2.5 mpg depending on the conditions. And I can tell there's more rolling resistance. but hey, they look so cool! Noise wise you can hear them at 45-60mph but by 65-70 they're about as quite as the stockers (very quiet) I think this tire is a really good option for an aggressive look but low noise. A hard combo to find. I also had them on my '02 HD and had good luck with that set. Last thing. I am really happy with the stance of these new trucks. On my '02 I had 1 1/2" spacers on the rear just to make them line up with the front better. It drove me nuts that the back axle was 2" too narrow. GM has that fixed now. everything lines up beautifully with the fenders/board/flaps. I should add clearance is good. .75" or more everywhere. I think I have full travel too. We will see how much things flex. But so far full lock and bumps haven't touched anywhere
  8. My '15 SLT Dmax

    Well I picked her up on the 22nd and I am trilled with the truck. I've put 1200 miles on and 800 of those towing my 4500lb fishing boat (which it totally dominates ). What a stallion of a truck. Awesome looking and I am in love with the coco dune interior. The steering wheel is incredible, soft thick & wonderful! I love the pad style buttons too. I do have a couple cons like the fact that pandora will blu tooth with android but not apple.... !?! Apple works fine plugged into usb and it also streams blutooth (anything, spotify, library, apps) through the "media" interface. but the pandora is not fully integrated trough blutooth (unless you use android arg!). anyway..... I am thrilled with the truck. Coming from a 6.2 that ran premium fuel which is equal or more $$$ (it was a good truck, i loved it to) I'm seeing my fuel economy has gone up consistantly 2-4 mpg. I had my last truck almost 4 years and know what it would get in a given scenerio. Or on a familiar route. For example I did a 100 mile round trip saturday I've done that route 50 times before. My 6.2 would do 16-17 on that drive, my new DMAX with just 1200miles on the clock did 20.8! FYI the DIC has been dead on so far with my hand calculations I'm low on time now but heres a few pics.... the 400mi is 50% towing/20% city/ 30% hwy empty
  9. 2015 color matched grille

    The center openings have white painted inserts. The stocker on my truck Is all chrome. So it is different. As far as the surround I don't know. Every HD has a chrome surround. Denali/SLT/all terrain etc..... Don't know if they make anything else Sent from my iPhone using Tapatalk
  10. Def low gauge on 2015

    Not a big deal if your dealer is less than 100 miles away. Mine is not. So I bought some Sent from my iPhone using Tapatalk
