Moving with hammie advice

Hiii!! I have a dwarf hamster, haru, he is the cutest thing. i am moving cross country this summer, driving 25 hours ( break in between for sleep ofc). i am VERY worried about driving with him for so long. i have a decent sized travel enclosure but i think the main thing im worried about is stress. i love haru, and want him to live a long healthy life. do any of you have advice on moving with a hammie? he doesn’t like anyone but me and has been quite aggressive with everyone else he has met so i dont think rehoming him is really an option, and i dont think i would want to do that either way. any advice is appreciated :((
