The white pine studs, roof structures that forms the so called trusses and cleats for most of the cabinets that's still in most of the sticks and staples rvs is soft wood and not much better than kindling for a fire place .In the old days house trailers were built with cheap materials and they were a fire trap. My company pioneered the use of fire resistant gypsum products, which we designed to only add minimal weight.
As far as the comments above, I can attest to that. Most every plant is a dangerous place to be.
Structurally in conjunction with the sorry fasteners and especially the short ones being used, owners needs to be mindful traveling on rough roads or stuff will fall always apart inside.
But gypsum and the intent of weight savings surely does not go hand in hand. But that sounds like an interesting career .
