Great lifestyle change, congratulations.
I love my troll, but what "constant problems" are you having with your present bike?
A bike is a bike, so without knowing more specifics of your problems, there is no guaranty a troll will eliminate issues if the problems come from how you ride or how you shift etc.
That said, a troll is a great, tough bike, as is the 29er ogre.
Given your projected plans, I would highly recommend getting more bike mechanic experience to be able to recognize the beginnings of mechanical issues before they become bigger, and how to deal with small things that can happen on your own on an isolated dirt chunkymonkey stoned road.
My derailleured troll has been extremely reliable and a stock troll comes with very sturdy wheels.
The troll and ogres are good, solid bikes that are indeed very versatile.
Gaining mechanic experience is like anything, it's a process and doesn't happen overnight.
Same with learning to be a mechanically sympathetic rider. Some people can be bull in a chinashop types and don't change, not good if you are in an isolated area alone.
