Santa Clause with a lift gate will be bringing my Buddy a little after Christmas. In preparation I've been reading up on the Brady Vac system and the are still a couple of things that I don't understand.
From the Brady's Tricks Blog:
"The foundation for the BradyVac I or II is a sheet of Trupan with a grid machined into it and flipped over with the smooth un-machined face pointing up"
Is the smooth side of the Trupan the spoiler board? What purpose do the machined grooves serve if they are facing the floor?
I'm very confused, any clarifications would be greatly appreciated.
Thanks,
Jim
