I pulled the plastic cover off the engine to verify that there is a transmission cooler and I am wired for OEM brake controller. I know the engine will pull it, I know the trans will hunt, but I wasn't sure about the coil vs leaf springs.
The rear coil spring makes for the best unloaded ride in a 150/1500 series truck, but they do tend to sag when trailering. There are companies that make stiffer replacement springs (TufTruckSprings.com) that slip right in, and of course there are Timbrens and air bag kits are available among many other options.
Basically, if you hauling near max payload in a Ram 1500 newer than 2009 (when they introduced the rear coils), you are likely to need some rear suspension add-ons.
I had a 2500 with the rear coils and found them to be very robust and not prone to sagging like the 1500s. The 2014 2500 I had with rear coils sagged less than the 2007 3500 SRW I had owned previously - and I tested and measured it with the same RV.
