New member.  I have a 2015 ram eco diesel that I bought new.  I joined to write about my problems with the sunroof.  Hopefully it will help someone out there.  I will be searching ways to tune my truck.  I pull a 7500lbs travel trailer and after the recalls she it not the same.  If anyone wants to know these trucks can be put through a good amount of work.  I towed my camper 4500 miles in 2 weeks.  From 118 degree heat climbing Arizona mountains to crossing up and over rockies a few times.  I didn't weigh the camper at the time but I believe it was around 8100-8300lbs.  I was a bit too heavy for the engine.  Some mountain passes I was stuck going 45-50mph.  But she made it!
