When Dave Weil moved into Mapleton Mobile Home Park in the late 1990s, the 1963 manufactured home he purchased was in such poor condition it wasn't livable, he says. Weil, 61, immediately rolled up his sleeves and began upgrading the single-wide, 10 by 50 foot unit. More than 20 years later he's getting design help with his newest renovation, which will make his home more energy efficient, thanks to CEDaR.
