DSDP Don summed it up perfectly.
I will add that having the tag axle will also give you a set of tires to transfer to the front if needed.
With our previous 42 ft. tag axle coach, I received a bad alignment once. I didn't realize it until 2,000 miles later. I was getting extensive wear along the inner edge on both front tires. The tires weren't ruined. I had a professional alignment done at TAFA (tire, axle, frame and alignment) in Nashville, TN. The best alignment I ever had and it lasted for years.
Anyway, I was able to move the tag axle tires that looked brand new to the front. The other choice would have been to take a set of the dually's on one side and switch them to replace the front tires.
The tag axle also helps against porpoising.
