We're in the process of upfitting a 3500 Dodge Ram cab and chassis.  I am trying to determine the ideal hitch height for my 5th wheel plate as there will be no height adjustment.  The only adjustment I will have will be on the actual 5th wheel RV.  I am guestimating that my plate needs to be about 50-52 inches from ground level.  As I think the trailer hitch plate is about 48 inches.  Can anyone give me some feedback on this?  Thanks.  

I can't help with the actual height, but can offer that when we ordered our rig, they had to flip the axles to lift the trailer to fit our 4X4 truck.

Thanks Luvglass.  Appreciate your reply....will continue to work on the upfit of the truck.  Take care.

In a "for what it is worth" manner, my rig is presently sitting exactly level and the pin plate is at 48 inches. If you are figuring for a 4 to 5 inch sag when hitched up, your numbers look about right. I don't think your truck will sag that much.
Keep in mind, there are some adjustments possible on most trailer suspensions. You can raise or lower the aspect of the trailer by repositioning the center of the suspension.
Good luck and level towing.
