I am looking at buying a travel trailer. I currently have a 2005 Chevy Suburban 1500 Z71. I don't know how much longer it will last as it is burning oil. I have been looking at used trucks but ...
All my GM trucks I have ever owned and still do, will burn some during towing. I change my oil when the meter tells me to on my 09. Usually around 7500 miles and im always down a quart, usually due to towing. Never more then this, also my MDX and Camry using about a quart between oil changes. All since new have been really cared for and not abused.
