Since it was rather warm today (~65°F), I got the extended sides framed out...
Covered in Coroplast on the sides and Foamular on top (interior shot)...
A quick mock up to the truck...
Mock up of the clear Suntuf roof panel fer the top gap cover...
A quick mock up of the side gap cover...
I still have the bottom of the extended sides to trim, tape the gaps, and paint them flat black.
Still braining a good setup fer the gap covers.
