I did not like the rear of the truck, could not add or release air with TC loaded.
Did not like wheel well. It gets too muddy in the winter months.
Did not like the fuel filler. If not located just right, they were bumped by the filler nozzle. Much preferred over the wheel well though.
Did not like one filler on each side of the truck. Walk back and fourth makes no sense to me.
I have found no disadvantage with both fillers in the cab out of the rain, mud and harms way. I can fill or remove air while inside or outside of the truck.
