Hello, I need everyone's input I'm trying to decide... I have found a 2001 suburban LT 4 wheel drive with the 6 liter with 140k on it. I also found a 03 burb with an 8.1 and 160k with the 03 being about 2k more in price. I will be towing what's in my sig an 08 rock wood sig ultra lite 31ft. 8 k loaded
I traded in my '03 8.0 Suburban for a 2011 6.0 Suburban and question whether the engine will hold up for 100K miles since it has to work so hard to tow my 7500 lb. TT. The slightest incline will cause it to shift down. And my towing mileage is the same for both; around 9 mpg and city driving around 10 or so. Highway is better but we are never on the highway without towing.
