I bought a 2018 Ram 3500 6.7L SRW CTD Laramie 4x4 long bed! I love it!! I am not used to so much luxury! It has and does everything, or so it seems. Just sold my 2004 Ram 2500, 15 yrs old, gonna sell my 2005 mustang, 14 yrs old, and I have a 1993 Jeep wrangler, 25 yrs old....so when I say luxury you can see what I mean.
I'm getting great mileage empty so far, constantly average over 20 mpg. Can't wait to see how it tows my trailer.

Anyway carry on....just thought I would share :-)

PS. already added nerf bars, mud flaps and my diamond plate tool box on the back, rubber bed mat, rubber tailgate mat.

 

Congrats! Nice truck. And you are getting 20MPG???? Wow. That's actually quite good for the newer diesels. (from what I understand of them at any rate.)
