Generally, any stick and tin trailer, like the Grey Wolf, will be entry level.
They will often have MSRPs under $20k.
Next level up will be filon-sided aluminum frame trailers, like Rockwood/Flagstaff. They often have MSRPs from $20k to $30k.
They will often have standard features that are options or not available on entry level trailers.
FR doesn't arrange their brands by levels.
You kinda have to look at features, options and prices.
