Thanks for your comment. I know it is a good pick. I am just wondering if I'd go with a 29 anyway because I think a 26 rigid is gonna be too bumpy on rough trail. What do you think?

Hello

I am new here and I am starting to shop  for a bike for bikepacking and the more I discuss with vendors, the more I am confused.

Here is the plan: about 6 months in South America (Ecuador to Chili), about 6 months in India, Nepal and Central Asia.
Bikepacking in remote places, singletracks, rocky grounds, etc. trails will be similar to, let's say, Colorado trail so no intend to stick on gravel roads.

At first I thought i'd get a 26' (parts are easier to find in central asia) hardtail but then realize the suspension might be a big problem if it breaks.
Then I thought a rigid 29' with 2-3' tires might do the trick. But there is still the wheel problem...

Rest of the components I am looking for:
Mechanical disk brakes
Preferably Shimano Deore or alike because it is easier to find spares and repairs
Gears with a very low ratio (no compacts!) but don't mind 1,2 or 3 brakets. I'll be climbing routes at an altitude of 4-5000m with stuff on the bike.
Steel/Cromoly frame or anything easy to fix
Possibility to put many bottle cage, anything cage would be great.
Simple mechanics

I must say the Surly Krampus looks good, but I am affraid with the wheels and the what if it breaks... even if I find a 26' spare WITH a disk brake, pretty sure my pedal would it the grounds, or the rocks!
My budget is 1500-2000$

I am curious to have your opinions, thanks a lot!
