Re: HELP, Towing 40'5th wheel with Ram 2500 4 x 4
Hello again,
The UVW is the "Unit Vehicle Weight". That is what you are supposed to weigh empty. It is then PLUS your water, PLUS your LP, and PLUS what you put in the trailer. The best way to know what it weighs is to take it to a scale. Lots of truck stops have scales. It will cost you a couple of bucks, but then you know for sure.
GVWR is what your trailer can weigh after you ADD all this up.
I don't know what your truck can tow, but your owners manual will tell you. IN THAT, Dodge will tell you the maximum weight then SUBTRACT for your weight and any passengers, including your dog.

Make sure to match up your truck with the charts and use the 5th wheel chart.
Personally, I think you are overloading or at maximum for a 3/4 ton Dodge truck.
Good Luck
