Our experience with late-model mobile homes has been that because they're built in a factory with tight tolerances rather than stick-built on site they're very tightly sealed...so much so that having a good carbon monoxide detector is much more important than with a relatvely drafty regular home. For those, like us, on a tight budget the realistic comparison even in a low-cost town like Cañon City is between a late-model mobile and a smaller and older stick-built house, many of which are "money pits" both in terms of needing ongoing work and for their high gas and electric bills, need to invest in new double-pane windows, etc. Cañon in particular has a large number of lovely older Victorians for sale at low prices - and those we know who've bought them live in discomfort (few or no closets, drafty, poorly insulated) and seem to put thousands into them every year.
Anyway, both mobiles and manufactured homes on a foundation are always going to be the choice of a small percentage of folks, but for those who plan to travel extensively - wanting a home base rather than all that goes with a home - or for minimalists and/or extreme cheapskates they can make sense. Where I see them really being of benefit is in high-cost places (like our old home of Boulder, Colorado) where they're the only affordble alternative to sharing walls in shoebox-sized condos or apartments with high HOA fees or tying up 400-500K in "starter" houses.
