Rotten Floor and C Channel

[Tim Cowles]

Hi,
I am new to this forum. I am installing a partial floor in my 2006 Safari, wood rot on OSB. My questions is do I need to screw the floor into the C channel? Or is screwing the floor down to the frame all I need to do. Not really wanting to take the inside panels off. Thanks!

To do it right, the floor is attached to the fram AND the C-channel is attached to the floor and frame. Of course mileage may vary as will the results depending on how you do the repair.

Thanks for your help. Would screwing up from underneath through the C channel and through the floor be a good idea?
