Hey guys just a quick question about towing. I have a 2007 Dodge Ram 1500 5.7l Hemi with the factory class 4 towing hitch. My question is how much trailer weight can i tow? i have a 23' boat that weighs 4000lbs + trailer, that i bought a week ago. ive already towed the boat once it seemed ok as long as i put it in to Tow mode on the truck. Mainly i just want to make sure that im not going to destroy my truck.
