So I'm thinking about getting into backpacking and so I've been reading up on all of the ultralight gear you can buy and make. Packing ultralight gear (Sleeping bag, backpack, tent, cook equipment, clothing, etc...) you can get your load weight (on your back) down to about 25 or 30lbs.
Do you think that touring and backpacking have enough overlap that you could get your touring weight down to 30 lbs?
If yes, what about for a cross-country (USA) trip?
What sacrifices do you think would be needed and would they be worth it?
Next, if weight were reduced to 30 lbs, do you think one could use a road-bike (Trek 1200) for touring instead of a touring bike? (I'm only 150lbs so that would be a total of 180lbs which seems fairly decent for a Trek 1200).
Finally, just in general terms, are road bikes such as the Trek 1200 suited to touring in terms of things like gearing and tires and durability and such? I've never been touring so I don't know what unique obstacles and demands on your bike that touring has in comparison to standard road-biking.
