Friend built hangers under his to store a 7 1/2 foot wheelchair ramp (removed from an old U-Haul). Carries other stuff under there too.
He worked 30+ years in the fabrication shop for R&D, so about all he needs is an idea about what is to be done, and he'll design and build something to do it with parts borrowed from where ever. Put power steering on a 30's vintage John Deere D, and did it again for his brother's Farmall, using '50s car parts.
All it takes is imagination, and a deaf ear to the why it won't work guys.
