"some other trucks of ours"
Translation:kekahi mau kalaka o kākou
There wasn't an option to report this correctly, so I'll post it here: There were two options given (listed bellow), and I chose the second, which, as far as I'm aware, is still a correct translation, just used in the context of "you and I". The original English translation does not indicate which "we" is being used in this context.
kekahi mau kalaka o kākou
kekahi mau kalaka o kāua
Mahalo nui iā ʻoe e Chasavaqe. You are totally right about the ambiguity of the "our/we" in the original sentence, and so both should be accepted. I've added "kāua" to the accepted answers. We'll see how long the Duolingo system takes to update.
