What is the mpg & towing capacity for a 2004 GMC Yukon XL (Vortec 5300 V8 engine) Model K15906?
mpg would be 14 city, 17 highway, and it can tow up to 7000 lbs. properly equipped (trailer brake is recommended above 2000 lbs.) also, make sure you push your tow/haul button so your transmission makes the proper shifts and does not engage overdirve unless it is safe- otherwise you will have transmission issues down the road. I hope this helps.
