2010 2500 ram single axle

5 or 6 would be better. Hope you didn't waste your money on a Cummins either, the hemi will do just fine

 

Did you ask that without using the "search" option and not looking through the forum just to see how bad you would get flamed?

 

Get a old stinger trailer and modify the truck with a rack and fifth wheel. Get rid of those junk 10 ply tires and put on some 4-6 ply tire. No need for a dually it will make you over weight I here the tundras are real good too.

 

Did the Cummins dealer cringe when you said CumminGs too?

Great! This means you won't know any better & will haul anything for less among the other hundreds doing the same thing starting up every single day. Have you researched anything within this business at all?

 

If you run a search on here you will see that there are about 2-3 per week like you who ask things like this. So that's why guys are messing with you.

Here's a nicer answer: The srw 2500 or 3500 trucks max out their rear tire rating on a 2 car gooseneck, so that's the max for them
