Been planning this project for a couple years now, about a month and a half to figure out, but I think I'm where I wanted it to be.
1. Ginrai (truck) combines with his trailer to form Super Ginrai.
2. Super Ginrai combines with God Bomber (trailer) to form God Ginrai.
3. God Ginrai combines with Ultra Bomber (trailer) to form Ultra Ginrai.
4. Ultra Ginrai combines with Ultimate Maximus (base) to form Ultimate Ginrai.
5. As a bonus, Ultra Bomber can also combine with Ultimate Maximus to form Ultimate Bomber.
BASE MODE
ULTIMATE GINRAI MODE
