The Knoxville Fire Department continues looking into exchanging their heavy rescue truck for a smaller, more useful one.  Knoxville Fire Chief Mike Roberts says their current heavy rescue truck is excessively heavy, has a very wide turning radius, and is impractical to maneuver on city streets, among other factors. The department did receive one bid on the truck,  and at a special meeting earlier this week the city council gave the fire department direction to go back to the broker to make a counter offer of $174,000,  $10,000 more than the offered price, and then to bring back a contract of purchase for the truck if the broker agrees.
