Limelight replied to TrailBoss1's topic in 6.6L Gas V8 & HD Transmission Powertrain (L8T/MYD)I towed with mine on day 2. IMO people overthink these things.
Limelight replied to Z71RAD88's topic in 6.6L Gas V8 & HD Transmission Powertrain (L8T/MYD)The towing difference between a 1500 and 2500 is night and day. No more looking in the mirrors for passing 18 wheelers that suck you into their lane, lol.
Limelight replied to Drumnatural's topic in 6.6L Gas V8 & HD Transmission Powertrain (L8T/MYD)I tow my 37’ camper - around 9000# loaded. This truck does a great job. Last trip I pulled the camper up I 70 over the mountain in 100 degree heat with the AC blaring. The engine temp actually went down, and the transmission temp went up like 10 degrees. This thing is a beast. One thing to note VS your old diesel. - it will rev a lot more. I was at 3000 - 3500 RPM for the entire climb at maybe 1/3 throttle. I had plenty of power to pass semis and slower traffic but you have to be willing to give it the boot.
Limelight replied to Carolina's topic in 6.6L Gas V8 & HD Transmission Powertrain (L8T/MYD)Love how this tows! First chance to pull the camper to Western Md and over some hills. This new V8 eats it for lunch. The grade braking is also phenomenal- I feel it’s calibrated perfectly! It seems the antigravity tires are working too. Lol stupid iPhone
Limelight replied to rickg gmparts's topic in 6.6L Gas V8 & HD Transmission Powertrain (L8T/MYD)Mine will give me like 200 miles and only burn 1/4 tank. Then it drops like a rock from there. It’s like a turbo- starts off slow and then wham! Kind of annoying but is is nice to drive for a few days without the needle moving. Ha!
It’s hard to beat the factory floor mats for fit and finish (the form fitting ones ). They fit perfectly and the mat for the back seats is just awesome.
Gotta admit- that looks damn good! I’m still super happy with my LTZ front end though.
I love mine so far- I traded from a 2019 1500 Z71 LTZ also. As you know, the difference while towing is incredible. I tow a 37’ camper ,8000#, with my gas 6.6. My truck has been rattle free. Every time I think I have a rattle it turns out to be something I stored somewhere, lol. It’s quiet enough inside that if I put my sunglasses on the dash I can here the little nose pieces rattling around. Drove me nuts until I figured it out. The ride is really well sorted out too. You can tell GM spent more time with the power train engineering than anything else. I like the ride better than my 1500 - a little firmer (I even have the heavy duty front suspension) but WAY better controlled body motions. I am very happy with my switch- the ONLY negative is a drop in fuel mileage, but I knew that going in. The 36 gallon tank makes it worth it. Hope that helps.
There are grommets already there on the firewall for that purpose- both sides! They have extended nipples ( lol) for the wiring to come through. You can barely see the passenger side grommet from the passenger footwell. I pushed a small metal wire right through it into the engine bay- then I taped my wire to it, put some dialectic grease around it and pulled it right through. Really easy.
