*We probably need to give him the Handle Animal skill, as the vehicle rules (from Dragon Magazine #294) for driving sleds relies on that skill.
For example...
Sled: Large vehicle; Handle Animal +2; Spd drawn (clumsy); Overall hp 40 (hardness 5); Overall AC 4; Atk (3d6, ram); Face 15 ft. by 5 ft.; Height 5 ft.; Crew 1; Weight 300 lb.; Cargo 1 ton; Cost 20 gp.
Drawn across ice or snow, the sled is an almost entirely exposed structure. The driver and any passengers gain one-quarter cover behind 1 inch of wood (hp 10, hardness 5). Eight riding dogs can pull the sled over ice or packed snow at a Speed of 40 feet even if it's fully loaded. Unracked snow slows their movement by one-half and deep snow cut it to one-quarter.
Worg Warsled: Huge vehicle; Handle Animal +2; Spd drawn (poor); Overall hp 100 (hardness 7); Overall AC 3; Atk (6d6, ram); Face 15 ft. by 10 ft.; Height 5 ft.; Crew 1 (plus three passengers); Weight 900 lb.; Cargo 700 lbs.; Cost 400 gp.
Goblins in snowy climes use their worg allies to pull massive sleds covered with makeshift armor and spikes. The driver and passengers aboard such a warsled gain threee-quarters cover behind a mix of steel and wood (hp 20, hardness 7). Two worgs abreast pull the sled at a Speed of 35 feet.
