The DaimlerChrysler Commercial Buses North America SLF 200 (usually shortened to SLF) is a low floor midibus. The bus was the product of a joint venture between Mayflower Corporation subsidiaries Walter Alexander Coachbuilders and Dennis Bus and Coach and Freightliner subsidiary Thomas Built Buses.[1] The joint venture was known as Thomas Dennis. Beginning in 2003, the SLF was sold via the Orion direct sales organization and through DaimlerChrysler Commercial Bus dealers. All SLF buses under DaimlerChrysler received the "SLF200" badge in lieu of the Thomas badge.

Design

The Thomas Dennis SLF was a left-hand drive version of the Dennis Dart SLF with an Alexander ALX200 body. The first few demonstrators and prototypes were fully built in the United Kingdom by Dennis and Alexander. Later buses were manufactured overseas and then delivered to the United States in a completely knocked down (CKD) form with final assembly at the Thomas plant in Greensboro, North Carolina.[2] Full production at the North Carolina plant eventually followed.
The early demonstrators and prototypes had lower profile front and rear bumpers. Some production units would keep these bumpers, but others would sport the thicker bumpers commonly found on other North American buses.

When the 35 foot SLF 235 was introduced, the radiator was moved from the open side to the closed side. The larger radiator protruded into the passenger cabin and took up some of the space for the two rearmost closed side seats. Therefore, those seats were moved up.
All SLF models used a roof mounted HVAC, except for the CNG-powered SLF 232. The bus sported roof mounted CNG tanks in an enclosure with the HVAC moved to the space behind the rear seats. This also added length to the bus.
As a DaimlerChrysler product, the SLF was made available with a four or six cylinder Mercedes-Benz engine. The SLF 230's engine compartment was modified with the radiator moved to the closed side, but unlike the SLF 235, it did not intrude into the rearmost row of seats. This model was known as the SLF 229.
