I think you've already identified the things that you need to consider, which is half of the battle. Experience gained riding the tandem is the other half, assuming that your tandem is suitable for the task at hand, e.g., frame/fork stability, wheel durability, adequate brakes, tires, gearing, and proper loading / weight distribution of any luggage.
You might try to make contact with Paul Parry in the UK who did a 5,600 solo tandem fund raising tour from Oslo, Norway to Bee, Nebraska back in 2004 to see what suggestions / tips he might have.
