Would anyone finance a truck for someone with no credit?

My boyfriend is 21 and has absolutely no credit. He’s been driving a POS truck since we met and he has had his current job for about three months and now is saving up enough money to get a better truck. The only problem is we’re worried no one will finance him because he has no credit. No one will give him a credit card because of it and the only reason he wants to finance the truck is to build up credit so he might actually be approved for a mortgage loan in a couple of years.

Are there places out there that will finance a truck if he were to put half down even if he has no credit? We have no one that has good enough credit to cosign with him and we feel like he’s stuck. What other options does he have?
