I don't have a Ram, but since you are not getting much response, I will say that it should be doable. The 5.7 hemi is a powerful engine, the 6-speed with tow/haul should pull well.
If you are climbing steep grades, towing 10,000 lbs., you might not be the first one to the top, just take your time.
The 14 2500 should handle 2,000 plus pin weight.
