Mobile Home Values

I would like to know where everyone finds out the value of a used

mobile Home.

I was told they were listed in a NADA guide, but I am having a problem finding them.

So I need someone what is the best way to find the value.

The mobile home we are looking out is a 1993, very good condition,

already set up, but I don’t knw the manufacturer.

So what other information do I need so I can find the value.
