dude, you're like going at this all backwards-like.

"i've never really bike toured, but i like bikes, and i wanna go on a tour,
but i don't really know where or what kind of terrain, and i don't know
what or how much i wanna carry.......gosh, i really don't know what any
of my needs are........so, help me choose a bike!"

you say "asia" like that's some homogenous entity. well, where the
heck in asia? singapore or mongolia? tibet or ****et? burma or japan?

i'd skip the camping part altogether, cut out that weight. in some countries
camping is not permitted, not safe, not practical....do you know which ones?
in general (there are exceptions of course) you 'should' be able to find
suitable lodging within daily ride-able intervals for $5-10. it's not that
hard to research a route........start with cgoab.

can you fix a bike? do you know what tools and spares to carry? don't
expect to find bike shops everywhere. and if you do find one, don't
expect it to have spares. or a mechanic. or tools.

i won't recommend a bike for you, since i don't know your requirements.
i'll just tell you what i ride here: large-frame (23") MTB. formerly a
diamondback wildwood, currently a BMC alpenchallenge. deore components,
26" wheels. v-brake front, mech disc rear. rear bags with about 5kg each,
h-bar bag with about 2kg. no camping or cooking gear.

i ride: thailand, cambodia, laos, myanmar, malaysia, singapore, vietnam,
southern china.
