The goal with the diamonds is to create a single web of material from corner to corner. In theory the belly pan could just be the two corner to corner strips without issue. The bellypan really isn't loaded in any other direction (aside from component weight), and additional material doesn't really contribute. It's worth noting our superstructure generally places a crossmember somewhere along the frame which helps the front/rear crossmembers a lot.

Also, we consider the bellypan integral to the frame, so rivets are a much lighter and faster mate.

If the extra strength isn't needed then please ignore my suggestion If the frame rails need more support to resist bending, then it may be worth considering.

No doubt rivets are lighter and work well. Rivnuts are simply my general preference.
