What are u or would you use to tow this 26 Tbud trailer..

Skip - nobody doubted the power. Most new 1/2T can pull it easily, its the payload and weights that are the problem with the majority of 1/2T trucks. You obviously have the HD Payload package with 2550 in payload, the OP is looking at the non HD package and will probably be over payload. Truck will probably handle it just fine, but technically it will be over.
