A 2015 RAM is a 4th gen and this is for 5th gen RAMs, starting in 2019.
I would think the dealer would know how to change the oil without making a massive mess. Maybe you should just tell them to do better.
Don't know about 4th Gen but 5th Gen oil udders work great for the oil utter.any tips to keep the oil from an oil change ( by dealer ) from getting into my electric power steering connecter ?
