Thanks for you comment on this Larry - My point is that as you have pointed out the corrugation takes the load ... so the flat part between the corrugations ... does not do very much ... if a hole is cut .. lets say about 3/4 down from the first bend of the corrugation (the edge of the hole - the centre of the hole would be in the middle between each corrugation) ... and you also press a 45 deg flange on the hole edge ... That might actually make it stronger in bending ? Would be interesting to hear others opinion on this ...
You may be right, but I would want an Engineer's perspective. I just think the risk/reward issue is off here. You gain very little in weight saving with this approach.
If you want to reduce the weight, cut the excess off of the top. And make them the same width as in the RV4. Sitting in them, you will never notice the difference, but loading baggage will be easier and you will have more elbow room.
With the altered cushions added in, you will lose pounds, not ounces.

I noticed you have plate nuts installed in the seat back. Are you willing to share what those are used for?
Sorry about the thread drift.
