    Is this unit equipped with auto temp control in the cab? (Does your temp selector show only hot and cold or does it show numerical values).

    If it's just the bunk unit that freezes up, replace the bunk expansion valve. If both the front and rear freeze up, it's either low on Freon or the compressor is going bad.
