Uyilo lwesivalo se-trunk luchaphazela ngokuthe ngqo umphumo wemodeli, ukutywinwa, intsimi ebonakalayo kunye nokulawula ingxolo yesithuthi.Kukwakho nezinto ezininzi ekufuneka ziqwalaselwe kuyilo lolwakhiwo lwesiciko sesutikheyisi kunye nokubekwa kwezincedisi, kungekuphela nje ukuqinisekisa ulungelelwaniso lwesiciko sesutikheyisi kunye nesithuthi, kodwa nokuqinisekisa iimfuno zobugcisa zesivalo sesutikheyisi ngokwaso.
Indibano edityanisiweyo yesigqubuthelo sesuitcase ibandakanya iipaneli zangaphakathi nangaphandle zesigqubuthelo sesutikheyisi (ekwaziwa ngokuba zizikhumba zangaphakathi nezingaphandle), kunye neendawo eziqinisiweyo zesigqubuthelo sesuitcase.Licwecwe lentsimbi edityanisiweyo yendibano kwimo epeyintiweyo iyonke kwaye ingadityaniswanga, kwaye sisikhokelo esisisiseko sokuqonda isiphumo somfanekiso wonke, ukomelela, ukuqina kunye nokufakelwa kwezincedisi zesutikhesi.
Njengenxalenye yemoto, isiciko se-trunk yeyona nto yahlukeneyo kwaye eyona nto ichaphazelekayo ngasemva kumzimba wemoto.Ngakolunye uhlangothi, isiciko se-trunk siyinxalenye ebalulekileyo yesakhiwo somzimba, isitayela sayo sesitayela, amandla, ukuqina, ukuthembeka kunye neteknoloji kufuneka ihlangabezane neemfuno zokusebenza komzimba wonke;Ngakolunye uhlangothi, ibala elibonakalayo, ukhuseleko, ukutywinwa kunye nokunye ukusebenza kwesakhiwo se-trunk lid ngokwayo kunempembelelo enkulu ekusebenzeni kwesakhiwo somzimba wonke, kwaye ikwayinxalenye ebalulekileyo yeemfuno zokusebenza kwesivalo se-trunk.
