I've been looking to buy a new truck for over a year now. This will be the second most expensive thing I've ever purchased aside from the house, so I'm doing more than due diligence in research. I can't speak from experience but I can speak from long hours behind the screen reading other's experience. My research indicates that the Cummins they are putting in the Rams is the best diesel pickup engine currently on the market. The transmissions they are putting in the Rams, is not. The best transmission can be found in the GM trucks with the Allison transmission. Also the Ram trucks have suffered in recent years with poor quality plastics. Ram, GM, and Ford have all really upped their game in past few years. They all have their high points and low points, but none of the low points are low enough to be deal breaker and none of the high points yield a clear winner. It's a really tough call. I lean toward Ram one day, Ford the next. But 4 days out of the week I lean toward the Duramax. And then some weeks I spend swearing off the diesels entirely. While the "Big 3" have been spending so much time and money to improve their diesel game, they've been spend as much time improving their HD gasser game, and the EPA has been doing their damndest to make the cost of ownership of a diesel no longer make sense for anyone except those who tow heavy trailers for a living. Don't go straight for diesel without giving the gassers a fair evaluation. The HD gas trucks can tow nearly as much, cost less, and cost less to operate.
One last note, if you do get the Ram, let me know if it comes standard with an invisible trailer hitched to it. It seems like once someone buys a Ram, they lose their ability to drive down the road without the tow mirrors sticking out into oncoming traffic.
