You don't say what year your Ram is. My '06 CTD has a hitch capacity of 1200 lbs some class IV's are only rated at 1000 lbs. My tongue weight is a hair over 1200 and, I'm not too worried about the hitch. I use a 1400/14,000 Equal-i-zer and am very happy with the way it preforms.
I have a fiberglass shell on my truck that might weigh 2-300 lbs. With that, a tool box, me and a couple of dogs, my truck, hitched up weighs 9100 lbs. 100 lbs over the GVWR. I am well under my GAWR front and rear but the GVWR is maxed out. My TT weighs between 9-10,000.
You may want to seriously consider going to a class V hitch and weigh your TV with the TT attached and see where you are for GVW.
I bought my truck new in '06. If I were to do it over I would have bought a SRW 1 ton. Hindsight is always 20/20. It is my understanding that the only difference between the 2500 and the SRW 3500 is an extra spring pack on the rear but, I don't have the facts to back that up.
I have no doubt your truck will handle it and a 1400/14,000 Equal-i-zer should work well for you. I don't believe you mentioned whether you have the diesel. You may want to check your total weights just so you know.
