[spinning wheels]

I hope some of you can answer this question. I have been looking (not very hard I might add) for a 67-72 motorhome. The kind with the one ton chassis, dual rear axle with truck front end. Now here is the question. I came across an ad for a 1972 Chevy Fireball. Has anyone ever heard of it? I haven't been able to contact the owner. I'm just hoping that this is the truck with the motorhome .
Thanks for any input on this question.
