My Stepfather's 2018 5.3 gets about 20 mpg @70 mph , no idea what gear. My 2018 6.2 w/3.42 gets 22 mpg or a little more sometimes around 70 mph.

I guess it mostly brand loyalty. I almost bought a Tundra and it's a sweet truck. The gas mileage on the Tundra sucks . Previous models I've owned; 1989 Silverado z71 reg cab 4wd 1997 Silverado z71 ext cab 2wd(Mistake not to have 4wd) 2006 Silverado z71 ext cab 4wd LT3 (loved this truck) 2018 Silverado z71 6.2l Crew cab LTZ, max tow(Loving this truck)

I going to have to try heating next time I'm off work. Thanks for all the Responses.

Thanks, I'll take it back out today and trim it.

2018 LTZ Crew cab. I have the "Weather tech "style GM floor mat on the driver's side and it won't lay down against the console. Does anyone have any ideas on how to get it to lay down? Has anyone modified the rear one so it doesn't run all the way under the under seat storage tray? It's a pain to get out to clean.

I really like changing own oil. I'm also a little OCD too. The 2 problems I have having the dealer doing the oil changes. #1 the whole process driving to and from the appointment. 1.5 hours waiting. #2 High pressure sales , somehow I need 25 things done to a vehicle that doesn't have that many miles on it. Lots of times they are purely taking advantage you.

I ran across this a while back. My LTZ has the full featured steering wheel, but it was very interesting.

I don't have a bunch of mods to my new to me truck. I'm going to do some small things later this year.

This is my new to me 2018 Z71 LTZ 6.2l .

Thanks for the pictures Ravenkeeper !

I have a tonneau cover. I may explore making a bracket to go under the edge of the cover. I will have a short run of coax that way. The P25 W3 Astro spectra is VHF ,its the higher split VHF. I can still go out of band to ham band ok. It's a 599 Flash,if you know anything about Spectra's . This is the best Flashcode.

I'll look at the cab vent ,I did not think about that. I don't think I have the Bose sub. I'm going to mount the W3 Astro Spectra VHF P25 under the rear seat and the XPR4550 UHF DMR(remote head) under the rear seat. I my use an XTVA for my 800,not sure yet on that. I want to use a NMO roof mount ,but its a hard decision to drill the holes right now with this new truck Thanks , KJ4SZO

Hello I am a NEW user. Does anyone here have any suggestions on a access holes to the cab for a 2018 Silverado LTZ to run power and Antennas ? I'm a Hamradio operator and public safety ,so I have 2-3 radios to mount. This was much easier in my 2006 Silverado Z71 LT3. James A.
