My opinion. I off-road very frequently. I live in New York and am currently in Reno. I drove out to go to Moab. Discovered an oil leak. Drove back to Albuquerque to the dealer. Immediately received a Hertz rental at no charge. Kept it overnight, in the morning found it was a loose oil filter. Extended GMPP warranty = No Charge.
I told you I am currently in Reno. Drove the Rubicon with the group. We drove to the dealer after I felt what seemed like all wheels locked. When he mentioned my Fabtechs, I was getting ready for a hosing. I needed Pittman and idler arms, ball joints and tie rods, rear sway bar hanger. Oh, and a transfer case. Extended GMPP Warranty = No Charge.
I negotiated with my dealer from a $3400 cost to $1900. Go here

Saving a few hundred by going to anyone but GMPP, is being penny wise and pound foolish. I had a 24-48 hour delay until the adjuster came out. How long would you have to wait when the non-GMPP stops doing business.
If you don't use your truck the way I do, don't spend the money.
Just my thoughts.
