Sure. Millions of Americans reside in "trailer parks" at a standard of living that is the envy of much of the world, and surely orders of magnitude better than the situation in Cite de Dieu. Also, on their own terms, probably the envy of many a Manhattanite.

Haitians aren't looking for 2-car garages and island kitchens. Running water, electricity, and a structure that won't collapse in the next natural disaster would do just fine.

I imagine a challenge with deploying manufactured housing to Haiti is that anything new that's built needs to be earthquake-resistant.
