Ohio Man Buried Riding His Harley-Davidson Motorcyle

This may be a creepy question but it is a grave. I think the idea is cool, but there looks like there is a lot of space inside the glass case. Did you make a vault too. If not how thick is the plexiglass etc.? Any chance of it eventually giving way? If so it looks like a lot of dirt could sink out of the grave in a hurry.
