However, the same amount of space will be taken by the 4-6Vs as 4-12Vs which would give you higher total load capacity.
3. On page 1, top left corner, of Thor Owner Resources Spec Document TRF1008-01.PDF, the wood product under the TPO is 2.7mm [=~0.106in=~1/10th in.]LAUAN. Under that is Foam/Frame, and then a ceiling panel of 1/4in vinyl covered wood. The aluminum frame is 1x1.5x0.04in square tubing. I highly suggest that you download this document prior to mounting anything to the roof as it also gives all specs & dimensions on the roof assembly. I used sheet metal screws through the C-channels into the aluminum, with lots of DICOR.

3a. 2.7mm sounds too thin to mount to, or even stand on. Maybe other models are thicker or the "rafters" are spaced closed to each other...
3b. I searched for this document in the Owner's Resource Vehicle Documents, couldn't find anything. I may need to call Thor to obtain.
