Lifestyle 5th wheel question

I just took delevery of a '15 Lifestyle LS36FW two weeks ago. It had the 8,000 lb axles with disk brakes. The tire's rating went up to the 'H' rated tires. The GVWR went up to 19,100 lbs! The disk brakes are awesome. I had to back the gain down so as not to lock the brakes on the LS. It is a great feeling not to worry about tires, and brakes. It's a good option! BTW, my old 5ver had E rated tires and I had to two blow outs, lost the tread on another which I found accidently when at a roadside rest stop when I noticed the black streakes down the side of my fiver, and another flat of which I don't remember why.

Spend the coin and get the axle upgrade. It's a good investment.
