Help pick a name

This is Colin’s work truck. Our other vehicles have names (Rocky and Henry) which are important to Jackson. The other day he asked what Daddy’s truck’s name was. So, we need to pick a name out. We asked Jackson what he thought the truck should be called and he said “Big”. We’d love some help thinking of names. The truck is big, it’s 4 wheel drive, it’s always dirty, and it has to go through bumpy and muddy construction sites. Another direction you might go in is that Terracon sounds like some kind of dinosaur. Thank you for your help.
