People who live in trailers and other 'manufactured housing' constructed before 1976 are eligible for a $7,500 tax credit on a new energy-efficient unit.
The new trailer has to be Energy Star rated, and the old trailer has to be destroyed as the aim is to reduce the number of inefficient trailers out there.
In general, a four-person household has to have income of less than $44,000 a year to take the credit. The actual amount could vary from state to state.
