I would highly recommend wider tires. Can you fit anything larger than 25mm? I'd go as wide as you can, maybe you can fit 32mm. If those don't fit, I would at least do 28's.
You definitely need to carry a spare tube and be prepared to fix a flat. That Trek should fit a 28mm tire but the trip is definitely doable with the current tires
