Has anyone had any problems with an 8.1 Vortex with an Allison Transmission in a one ton truck.

I have a 2001 2500HD 8.1 Allison and love it! Only drawback is getting places to fuel it up. Getting an average mileage of 11-13 towing the 5th wheel and 16-17 without. Plus it's paid for and only has 91k miles.
