Aspen for Bedwood?

[DransportGarage]

In addition to playing with cars and trucks I do some woodworking, so I'll be cutting my own bedwood. I could use pine, but I don't care for how it takes a stain unevenly. I could use red oak, but it likes to split on the ends. So I thought about using aspen (available at Lowe's at half the price of red oak). I know it's a soft wood, but this truck will never haul anything. Is there any other reason not to use aspen? Has anyone else done this?

(If this question is high on the stupid meter, have some fun and rate from 1 to 10, with 10 being incoherent... )
Thanks,
