700-seat tourney with only one prize?

[Maple Leafs]

I've won a seat in a MTT this week being run by a local radio station. Winners gets a truck. As best I can tell, there are no other prizes.

How does this impact strategy? Do I just go kamikaze, or can I still sit back and be patient? Without any actual bubble, do big stacks lose their power to bully?

Also, somewhat related, is there anywhere that entries to these sorts of tourneys can be sold (if allowed by the tournament rules)?
