Lol. the only concern will be the door. Take it to the dealer and ask them to realign the door.
As far as the 1/2" difference measurements, i bet that is the driver side. A lot of vehicles lean a little more towards the driver side,especially when the gas tank and battery etc are on that side.
Google RAM Lean. is not news. maybe it's new for some of you buying a new RAM. per another thead from last year when somebody was concerned as well, this is not especific to RAM so don't dice on the model just because it might be news to you. Google "Jeep lean", or "Taco lean" or "FJ lean", "Tundra lean" etc etc etc. Different ways to address it, you can add a litte 1/2" spacer in the front, or be creative with a JK wedge spacer for example in the rear, be creative with airbags 1000 system for example, but split the hoses so you can pump more air in the rear driver side, in the JK's you can also play with adjustable sway bar links in the rear, etc etc. be aware that if you lift one corner the opposite side corner will go down just a tiny bit. Measure and see where you'll need the spacer, sometimes you can do one, or both on the same side front and rear. That's assuming you're anal about it. most don't even realize they have a lean until they measure. Seems to be more accentuated after a lift sometimes, i guess depending on how bad the lean was stock. Those of you with 33 gallon fuel tanks will more likely see the worst of the "RAM lean". All normal believe it or not so go easy on your dealer regarding the lean.
The door on the other side, be polite and ask them to fix it, should take less than an hour for the shop dudes to fix that.
Have fun.
