Althought this post has nothing to do with Sunline, I thought I would share this with you all.
I may have mentioned this before on this forum. I can't say how I know this, as I don't want to identify my current employer, but this is not just a wacky concept.
I know with about 90% certainty we will be seeing this in use in a short while. In fact, the RV industry has some unbelievable $ figures in repair warranty costs for structural issues dealing with floors, walls, etc. Not to mention the stress to make them lighter, so we can tow with less TV.
This will change the industry, and hopefully make it better for all of us. When I hear more I will try to add to the forum.
