I'm by no means an expert so take it for what it's worth. You will be in the 15000 lb.
area, I would think for safety you would be looking at a 3500. If it won't be your daily driver a dually would be better. Just my dimes worth, but I'm sure someone will say you have more truck than you need. Check you trucks specs, an see what you think.
Best of luck with your search.....
