I debadged mine. The remaining stickers can stay until an issues arise as they are ultimately just stickers. I run mine through the car wash quarterly and rinse mud off the undercarriage about weekly. Any heavy rain puddles 3 inches of rain from my office and I’ll purposely drive fast through it for the undercarriage too. I fill up twice weekly and wipe the inside down while waiting on the pump. You need to read the locker thread(about 39 down from this one) as it all you’ll need to know on that. Mention oil change and you’ll get 100 opinions. I buy Mobile 1 0w40 twenty gallons at a time along with 3 Napa Gold filters(Wix makes) which is three oil changes for $130. Some guy on the heavy duty thread put almost 500,000(all towing)on a 6.4 Hemi with Mobile 1 and retired it to the driveway. However, FCA recommends PUP but they also own Penzoil. Other things to know, it’s a 31 gallon tank but EVIC says you’re out at 25 gallons, no matter how low the windshield wiper tanks get it will never hold an entire gallon of $3 blue water and people will rubber neck looking at your truck. The ********* in the Rebel will wave every morning but the a$$hole in the jacked up Cummings won’t. That’s about all you need to know about your new PW. Best truck you’ll ever own!
