Gotten a phone survey from FCA about my purchase and one in the mail tonight from a outside company ..survey pertaining to my new truck purchase
Wow buddy, that's more mental torture than one guy should take. let me try to help as oppose to just making a comment. Take this time and do:
1. Get into the owners manual and all of the supplements and study
2. Have all of your add on's priced and lined up
3. Make a list of all the things you can think of ( even little things ) and present to your salesman for the service department to do. As well as having them check off the problems that other owners have experienced that might be headed off during pre-delivery. Example of that, have them check that hood shake/fifth wheel puck lining up/ software update on the HK stereo system if your getting that. Look over this forum and use it to your advantage for things to check. Some folks don't like the dealer to place their dealership sticker on the paint of the truck. It's little things like that you might think of, ( I learned this the hard way ).
4. If by chance this is your first 6.7, get all of your trinkets that you may need to change your own oil ( if you do that ) Genos is a good place as well as Amazon.
5. Get your financing lined up and check for your best rates. Last year I made 10-15 phone calls and wound up saving .050 over what I was going to accept as the going rate.
6. Shop for and research your tires. Some here say the tires are junk, so that means you may be looking sooner than later.
I'm sure you could come up with a few things yourself.
Good luck and post some pics. soon I hope.
