Ok, so it looks like I will be selling my 2005 Tahoe Z71 and as of today it looks like I am buying a 2018 2500HD Long Bed crewcab with Duramax/Allison combo with 24,500 miles. Any thoughts to share? When I can I will post pics of it.

 

now, you can tow pretty much anything.
they are great trucks until someone tunes it.

have you dealt much with the "new" aftertreatment systems

 

I have not dealt with the after treatment systems but am familiar. I know what fluid to buy for it and about how long it lasts. My original 2003 2500 HD did not have that.

 

they seem to do better in warm climates. service trucks that idle excessively with little highway driving seem to have the most problems.
