I also would not get the pistola in any circumstance for this type of thing. I am the same weight and planning to do some tours and won't think for a second about buying that bike. If you do decide to with it for some odd reason though buy a frames and not a built up bike as if you buy the complete pistola the wheels are the last thing in the world you would want for this you would want a different rear derailuer able to handle more difference in gearing than the short cage rear, you would probably want a triple and then also a new front derailuer. Also if you know your putting a rack on it why buy a bike with no eyelets or rack mounts? Also no room for fenders which you might want. The pistola isn't really what you are going to want I dont think, but good luck if you decide to get it.
