Trailer has 5x9 floor and walls are secured to floor with 2.5" deck screws every 4".
My questions are:
1. Is the 2x3 framing for walls and roof substantial at these dimensions? Roof is on 16" centers with the "Kregged" joints and inside width of 55".
2. Would 1/4" plywood be sufficient for roofing material and walls?


THANKS!
