wood or metal trusses
I know sales people will sometimes say whatever they think will sell the trailer- but are metal trusses really that much better than wood? What do you think?

When we went shopping for our Teardrop I looked for what failed in old trailers,(I come from a QC back ground) and found rust and wood rot.
I also wanted lite weight as we would be pulling it with a Subaru Outback. Ours has an all aluminum frame and the cabin is 1.5 X 1 X.060 aluminum frame stress panel construction and is strong enough to stand on. The one area of concern is that the floor is OSB (actually more waterproof than conventional plywood) which is wrapped in plastic sheeting. Forest River at least used to use Composidek which is impervious to water and would be the materiel of choice given a choice.
To sum up, what aint steel don't rust and what aint wood don't rot. You are building an aircraft not a tank and most RV manufacturers are stuck in the dark ages of construction methods.
