SAFETY. West Texas HWY speeds 80 mph +.

Have grandchildren with sporting equipment. I have a heavy boat and a steep slippery boat ramp. Family weekends and vacations need grandpa and his Yukon XL. Little ones watch movies on long trips. They are very quiet when occupied. Had suburbans from 1985 until Yukon XLs beginning 2001.

Nice Ride

I have owned Jeeps since the early 80's, but they did not have anything in their lineup that suited my taste. I wanted a full sized SUV and this is the mac-daddy of SUVs. The one I bought had the Denali trim and on top of that it had the Denali Ultimate package which gives you all the bells and whistles.

*****
Stylish and functional

We had a 2003 Yukon XL that served us so well and we are hoping this new one has the same reliability and performance. We love all of the bells and whistles this new one has.
