Anytime I see those clowns in the gold CRST trucks, whether they are pulling an STI or CRST trailers (CRST owns STI) I stay clear.
STI cons you with a contract that "says" you will make the "accessorial" charges in addition to mileage, but since CRST bought STI those charges...
I worked for them for years using my own truck. STI is owned by CRST, so you will have endless competition from all the thousands of gold CRST...
