GG1, that will be fine.
Doug,
I'll let you know. My brother has a pickup so if he is interested, I'm sure he will be able to pick it up. He also has a basement for a layout of about that size. In that sense he is luckier than me. In AZ we don't have basements and I model scale O. Two strikes on my modeling!
