Bullshit, peckerwood is a prison gang term and a term used to call someone racist as fuck. It is uglier in my opinion because it's a derogatory descriptor for the character and race of an individual. There really is no difference.

You may feel that way, but 'peckerwood' is a far less offensive term than 'white trash'.  It's also not generally used to demean a person, but rather their lifestyle choices or their perceived values - something that 'white trash' can be used to explicitly demean the individual.
