with brakes it will be fine but ill tell ya what the difference between my duramac dually and my 2500 with the 454 is night and day. That thing will pull an enclosed box like shit.

find an f250 or f350 super duty diesel 4x4 non dually and that will be great.. btw down in FL here i never had an issue with my dually being a pain in the ass at all. Always 5x more parting then needed at stores , wide straight flat roads ect. You have rode around in traffic with my dually. Once your used to driving it its like its not any different then a normal truck and normal trucks then feel weird.
