THIS IS A 1996 FREIGHTLINER IM AM BUYING OFF OF BUSKE LINES INC. I WAS IN A RESTURANT EATING IN A RESTURANT IN INDIANA. I WAS NOTIFIED THAT UNIT WAS ON FIRE. I RAN TO TRUCK AND FIRE HAD GUTTED INSIDE OF CAB MY DOG WAS TRAPPED IN THE SLEEPER AND WAS KILLED I NOTICED NO SMOKE WHEN I LEFT TRUCK BUT SMELLED SOMETHING LIKE HOT PLASTIC I CHECKED BUT DID NOT FIND ANYTHING BURNING. TRUCK WAS THEN TOWED TO ST LOUIS MO I WAS INFORMED BY FIRE DEPT AND SHERRIF THAT IF I WOULD OF LAID DOWN I WOULD HAVE PROBELY BEEN KILLED DUE TO TOXIC FUMES PRODUCED BY SMOKE. IN RECENT MONTHS I HAVE SEEN IN PERSON A MINIMUM OF 10 OTHER TRUCKS SAME YEAR AND MODEL WITH SAME FIRE DAMAGE STARTING IN THE SAME AREA.
