I'm 6 days into the new truck and have a few likes/dislikes. Very minor and mostly personal. At this time very happy with the purchase and time will tell on the Gen3 motor.... only got about 150 miles on it so far, but averaging 24mpg and that's short highway and town riding and around Boston the highway riding is always stop and go. I will continue to post more as time goes on and look forward to others feedback as well.

The ride and interior can't be beat. This thing is VERY quiet on the highway and handles like a dream
technology is beyond what I could ever want and free wifi for 3 months or (I think 3 GB of data) is pretty cool
1 year of Sirius Guardian to control things like locking the truck, cranking the truck from anywhere you have wifi on the phone is cool.
Ability from the smart phone search for a location on a map and send it to the truck, so when you pop in the truck the Nav is prompting you to click ok to take you to your destination is another great feature.
Tailgate, love it.... easy access without having to reach over the bed... while I haven't had any issues reaching over beds for the past 40 years, it is certainly convenient to be able to swing the door open and no reach...

Moon roof is absolutely stunning and huge. and speaking of huge the back seat is very large and I could see myself riding back there on a cross country trip. Very comfy, roomy and heated and cooled seats... very nice.
Dislikes:
Trailer tow mirrors. This may be something I get used to but they are too big. When I ordered the truck I saw that it mentioned "Power Trailer-Tow Mirrors with Manual Fold-Away" I took that to be Power folding mirrors with fold out for trailer towing since the mirror fold up and out for wider view for trailer towing. This is my biggest pet peeve now and I've asked the dealership to price out replacing them with the standard power fold mirrors. While this is on me since I ordered them without researching totally, they are barely able to fit into my stock sized garage door opening. A friend of mines' son has already ripped this same type mirror off the passenger side of his 2018 ED Limited last week. I will be very careful, but if my wife or son jumped in and backed out of the garage... I could see that happening.
Rambox is warped on the passenger side and the regional manager wants to see and document it in person to open up a case with FCA. While its on the front of the passenger side of the rambox I'm hoping it doesn't catch water and leak. Hoping they take care of this asap.
