The upper rail caps need to have a rolling bevel cut so the planking can sit flat – much more curvature on topside as opposed to bottom. Decided that vent and leash tether would use solid blocking and everything else EPS foam. Was hesitant to trust EPS but all research say it is excellent and more than adequate structurally – guess we will find out.
