I think age is a bigger factor than MH type.
MHs lose the most in the first few years and then level off. I see $1,000,000 Prevosts going for 1/2 price in less than 10 years. Same for garden variety DPs and gassers. They all lose about the same percentage - give or take a few points. In terms of real dollars, gassers lose the least in the first few years (50% of $100K is only $50K), then DPs (50% of $250K is $125K) and then luxury coaches lose the most (50% of $1M is $500K).
Just get comfortable with the losses before you buy. Then remember: Your losses are hypothetical until you sell. Then they are REAL.
