Good Choice! Enjoy the Ride.
We've towed Cruisers with RAM heavy duty trucks for over 25,000 miles. We spend much time in the Rocky Mountains and the 2012 RAM 3500 diesel gets some hard workouts pulling over Dead Indian Pass, Sylvan Pass, McDonald Pass, Powder River Pass and Homestake Pass plus others.
1,To avoid injector problems we use Stanadyne faithfully.
2,If the batteries need changing make sure to follow procedures; a new ECM is costly.
3, Pull the radiator cowling once and awhile and hose out the 5 lbs of bugs that are causing the cooling fan to run more often.
4, If you hear an odd noise from under the hood check your water pump. They don't always leak before failure.
5, For the hell of it and when not towing take her up to 30 mph, step down hard and hang on. Darn if i don't love those 300+ horses.
