The Bleriot is not an expedition touring bike and if you are over 200lbs and want to carry 100lbs of gear it would not be a good choice, but for regular road touring it's as good as anything and better than most.
Put a couple of panniers front and rear and you will be fine. Here's an example

Both the Saluki and Bleriot have nice touring geometries with long chainstays and are solid bikes good for long distance touring
I may be too heavy. I weigh 255 and am 6'3" tall. How long do chainstays need to be? I've got a nice Jamis Coda Comp and they are 410 mm.
