Any new Ram Owners?

I have a 2010 Hemi 5.7 that I have owned since new. Just turned 200,000 miles on original motor and transmission. Have replaced brakes and shocks obviously, but the list of replacements to this point have been:
water pump at 80,000 miles, I did that one myself.
New radiator as the old one was weeping.
New fuel pump just a few miles ago as the old one was starting to act up so replaced to not get stranded.
rear pinion seal was done under warranty.
two starters but that was easy and did myself. Thought it was a battery at first but it was the starter.

I have had a diablo tuner on it since the day i got it and have always had MDS turned off. I didn't think it was worth the hassle having loss of cylinders for minimal MPG gains.
I have used Mobil1 since new and use 7.5 qts. every 6 or 7k miles.
I'm trying my best to get to 250 or maybe even 300 on this drivetrain and would consider rebuilding since the body is pretty good. I mean my truck is 12 years old and they still make the same body style sold as new, even though it's the older version. I remember buying this and there were very few new rams out and they were still a distant third in sales each year. How things have changed.
