Not sure that I’m a good reference for a RAM 2500. I’ve never owned a vehicle any larger than a Tacoma.
What is your reservation with a smaller camper? In my opinion, a Hawk would be a mansion considering my wife and I live out of a 5 foot bed camper. Granted I know that’s not everyone’s experience, but still.
We have found that we can do more with less. Less stuff being brought with means less hassle, less camp setup time, less mental and physical clutter, etc. In the end, you’ve gotta do what works for you and what you’re comfortable with. The good news is that you should have zero issues on payload of gvwr on a ram 2500.
