"Question for TCHAZZARD.
Is the mango seal from the bottom will you get wheel splash from below in the rain? Looks like an interesting vehicle, I'm looking forward to reading your updates and experiences with it."

There are cutaways in the bottom to allow one to push themselves backwards. This said, there is no wheel splash as the wheels are outside of this cutout area. Another benefit is that the entire drivetrain is enclosed. This will dramtically decrease winter maintenance.
