Greetings Sportsmobile fans! Just thought I would add a thread on my custom build underfloor storage boxes (made by a member here....can't remember his member name) But thought I would show my install of TWO underfloor storage boxes in a Extended Body VAN!!! IT CAN BE DONE!!! You will have to cutout and replace a frame support and move it more forward on the frame to accommodate the rear box as well as remove the spare tire mount. But it all Worked GREAT!
Starts out like something like this, very interesting picture here.....
then start will two beautifully built aluminum boxes,
Specs: DON'T TAKE MY EXACT WORD FOR SIZES, I WILL NEED TO CONFIRM
FRONT BOX(closer to rear doors):
14" wide x 17" deep x 32" built out of .125" 5052 alu. Cut opening 14" x 24"
1" vertical flange around opening.
REAR BOX:
15"wide x 15" deep x 32" built out of .125" 5052 alu. Cut opening 12" x 24"
Then start cutting away!
Mount and set in place, I used 1/2 grade 8 bolts through the boxes
Look from Underneath
ENJOY!!!
