I have a lot of experience with tru products so I would be happy to field any questions you might have.
The park owners in my area love them because they're cheaply priced and they are a great alternative to purchasing repossessed or used homes. You can purchase a 3 bed/2 bath 14x66 box for under $19K delivered within 3 hours of the plant. A 2 bedroom/1 bath can be had for under $16k. That price will include Vinyl windows, Vinyl Siding, Shingle Roof, Zone 3 insulation, House type door w/ storm door, and a dishwasher. Your going to have ABS (plastic) 3 piece tubs and surrounds, and cheap but functional faucets and fixtures, and short laminate scab cabinets. Floor Joists are spanned to a little over 19 inches to save on lumber.
From my experience they seem to be holding up just fine, and retail home buyers are quite happy with the products because they are getting a lot of bang for the buck. Many park operators feel the same.
The cheapest Legacy Home is going to run you about $8-10K more from what I can see. Yes it's a much nicer home, but if you are leasing them won't each sustain the same types of damages like holes in the walls, destroyed floor coverings, smokers that have yellowed everything?
Would love to hear some other opinions as well.
