Bicycle Mechanics - Trek Navigator 100 headset size? (1" or 1-1/8"?)

Can anyone confirm the headset size of a Trek Navigator 100 (2004)? Bikepedia lists it as 1-1/8 threadless, but it is threaded, so that obviously isn't correct.
I'm considering swapping out the fork and converting to threadless in the process, but I want to confirm its 1-1/8". I don't have access to calipers, and I'd prefer not to disassemble it unnessarily if someone here can confirm the size.
I just noticed the top nut on the current headset lists 25.4 diameter. I'm gussing this is the quill diameter (making the headset 1-1/8") and NOT the steerer diameter (making the headset 1"). Can someone confirm?

Yes, the stem quill is 1" in diameter, I just put a caliper on my 2006 Trek Navigator. I'm interested in the responses to this question. My Navigator has 10,000+ miles on it and I've had to replace just about everything on it from wear or breakage. I haven't had to do anything to the stem yet, I've just cleaned and regreased it periodically.
I too have thought about replacing the threaded headset with a threadless, but considering the potential cost, I have doubts this is a good idea. I'm wondering if getting a better quality bike with a better front fork and a threadless headset might be a better option.
The head tube on my Navigator is quite long, 7 3/4 inches. I have another bike with a threadless headset and the head tube is 4 inches, which is what appears to be the most common length of head tube I see on new bikes with threadless headsets.
So there's a potential problem finding a fork with a steerer tube long enough for the long head tube(?). Also, I've read from other postings you should limit the new fork travel to about 100mm on such a conversion as anything greater might cause handling/geometry problems.
I ride my Navigator on both the street and rocky desert mountain trails. I managed to crack the front wheel rim on wheel no. 2. My front wheel no. 3 is a stronger upgrade. It would be nice to have better forks than the pogo-stick forks my Navigator came with. Or maybe I should just get a decent mountain bike for my trail rides.
I'm interested in any feedback, are we going in a bad direction here in considering this conversion?
