Trek's T2000 will apparently be fitted with a Bontrager carbon fork for '06 and comes standard with Shimano's R600 standard reach calipers. The fork uses a 1.125" steerer and, unless they changed their stock geometry, has ~55mm of rake, ala Santana & Burley's baseline tandems yielding between 1.9" (Med/Lrg) and 2.0" (Small only) of trail.

True Temper have said they can adjust their Alpha Q X2's fork leg lengths a few mm as a custom order but you would still be constrained by the very narrow wheel arch with respect to running tires much wider than 25mm.

However, I suspect if this is something that True Temper "will do", it may also be something Reynolds and/or Wound-Up "could do". Your best bet would be to call them and ask. Their tandem fork is produced with 45mm of rake, which is at the far end of the world from the Reynolds & Trek forks in terms of how they would alter the handling of the same tandem.
