There is no info on the pressure washers, they look like small cold water units, if that is the case, they should be asking about 1/2 of what they want.
If they are hot water rigs then they are still small and should be asking a lot less money than what they want.
Cold water rigs are cheap, that is a small trailer, there is really not much there, just a lot of stuff spread out to look like a lot.
Not bashing, just telling how it really is.
