both Salem and Grey Wolf are entry-level trailers. aluminum-sided wood-framed travel trailers are much cheaper to make than the fiberglass/aluminum framed trailers.
only by you going inside both brands, will you know which one is better quality.
every brand has its fans and quality is very subjective.
