Have driven the older Rams for years. Being a Dodge Parts Manager since 1994, I have seen likes and dislikes for this truck. Transmissons where garbage but now aftermarket rebuilding packages make this a very good work truck. I have a diesel with 365,000 miles on it. and the owner before me had the transmission rebuilt with heavy duty torque converter and hard parts. He did disconnect the locking torque convertor.
Diesel engine. Loads of torque. Decent on MPG. Roomy interior. Load this truck up with wood and it will pull for ever. 12 Valve diesel not the most peppy engine but will get you from point A-Z in a reasonable time
Have the trans done right and you will have years of hauling
