Looks good, I think I may have to double up also. I may even have the bed a tad bit higher on the inside to accommodate the twin drives. Leaving the sides extending down to conceal a higher bed bottom. I want to make it be able to dump a heaping over loaded bed. Not to say I'll always be overloading but never know
. I'll have to look if I have enough room for twins. Lou, is your set up in the frame rails of just above them? And the mobile screening plant is awesome!!!
