143k and starts right up

Just cleaned up my dog Emma's truck. She was a big 135lb Great Pyrenees mix that traveled and hiked with me. This truck never failed us. I bought it new. It was the start of the 4 door truck craze. We were off to the Dodge dealer to see the new 4 door p/u's and saw my truck at the dealer down the street, So glad I stopped. I still haven't driven a Ram. Rebuilt transmisson 105k; replaced hoses and water pump 134k; current oil/fluid changes every 5k Replaced headliner 138k; everything else is original and still works - 4.0

My Avalanche was extremely durable and reliable on the rugged back country roads. Cold Montana minus degree temps, she still fired right up. Despite the high miles it ran like a champ.
