I don't recall if you mentioned what gearing you have in your truck. Before we order I'm trying to determine if I can get by with the 3:55 or if I will need to get 3:92.
Love the economy your reporting along with the driving conditions...thanks.
Good question. I have the 3.55 gear with a 4x4 (ran 2wd the whole trip though)
I made it home tonight and filled today in South Carolina for $3.05 (saw it later for $2.99 a first for the whole country in SC) Climbed a bit up and down big hills and faced a head wind and rain all day. Sucked my 15.7 down to 14.3 on the refill. That makes 11 tanks to get back and with our unexpected detour south about 3800 miles total. I averaged all of them to get 14.7 going east. We got 14.4 going west so I guess thats about the best I can do for the way I drive.
A few other observations from the trip in no particular order
1) I found I really needed to do the lift foot off the gas trick almost always to get the truck to shift into 6,7,8 if I felt it had the RPMS to do so. The truck always seems happy using more diesel than it should
2) We used A LOT of DEF. We went about 8000 miles and used about 18 -20 gallons
3) I found the NAV really accurate directions wise but I HATED that it warned me of accidents 60 miles away literally every 3-4 minutes and those were always gone by the time I got there. I am sure there is a way to turn this off but I just cancelled guidance when it got annoying since I mostly knew where I was going until I needed it again. The voice input is terrible as well from myself and my wife who are born and raised in CA with no accents. It 80% of the time could not tell what we were saying.
4) I did find a feature on the NAV I really liked and that is the altimeter and GPS coordinates which can be found under the - Information, - Where are we?, -GPS button. I really like seeing the rate of climbs and decents and altitude we are at.
5) Comfort. I really like my plushy leather seats in the Laramie. My wife and I were always comfortable even on long days and never complained of weird back or neck issues like we have had in other cars. I also love the seat heater/ steering heater that comes on with the remote start from my trailer before we get ready to leave every morning.
6) Reliability. At 14,000 miles now I have had ZERO issues with the truck other than some weird electrical things early on that got fixed with a firmware update. I have really pushed the truck hard with over 3/4 of its life towing up and down 7000ft grades in the middle of the hot summer and now the cold weather. The transmission / engine/ turbo all seem rock solid to me. I know some posters have had some serious issues but clearly these trucks are not all bad so I wanted to speak up to say mine seems good.
7) Power to spare. We never had an issue wanting/ needing more power. No matter what the wind was, or what the grade was, this thing can pull with the cummins. We climbed every grade with the cruise control on and 100% of the time it maintained the speed as we blew past old 8 cyl trucks and big semi trucks towing going up hills
Thats it! Thanks for the looks and the questions. If there are any more I am happy to answer them. Thank you
