Re: 2500 duramax how much weight can i pull
 

Maybe look at the installation of equalizer bars if you are towing on the tongue. I have an F150 Supercrew 5.4 around 8700lb towing cap. and I tow right at 6500. I wanted it to ride alot better and the difference is actually incredible! I had them installed at a camper place and it was the only the 2nd time they had done it on a boat. After they tuned the hook ups and did a test drive, the install techs were extremely impressed. I didn't need to do this but for $300 it was some of the best money I have spent, and really worth it when it comes to my 4-5 hour rides to Table Rock Lake. They take all the "lunging and the bouncies" out going over overpasses and other bumps and depressions on the hwy. Oh and I usually over do everything i get my hands on. Make it right and bulletproof or don't do it at all....

I pulled a 43 NorTech on an Aluminum trailer a total of about 15000 miles in 03 and 04. Weight was 15000 lbs plus.It did a great job,could set the cruise in OD and it wouldnt shift down unless it was real windy or on a big overpass,and I always ran 75mph.A Dually would be more stable but in my opinion not worth the aggravation for everyday driving. I put Michelens on that were 10 ply,could inflate to 80lbs when towing,and back to 45lbs for everyday use and softer ride,worked for me.Great truck,still in my fleet.
