I had a heavy duty bumper with a receiver welded on the back of our 5th. I've carried 2 bicycles on it. You could click on my avatar and find the post, including pics.
I also installed a Curt front receiver on the Ram. It's a Curt that I bought through Amazon at a good discount to the Curt MSRP. No holes to drill. I did have to cut a square out of the plastic chin spoiler with a Dremel tool. I carry a bicycle on it when I use the cabover.
Here is a link to Curts' receivers. Not sure if it's your specific model. 500# tongue capacity.
