I only have one trust for everything and fail to see how two are better. Your trust should be the same for everything. A simple line that excludes any trustees from property that they are not legally allowed to own should be in any trust. For example, your minor children can't usually own your cars. I think the gun trust lawyers are just trying to sell more trusts.
Another issue is schedule A. My trust owns a lot of things and just because it is not on a schedule does not mean the trust does not own it. Schedule A is great for making a clear case of ownership but I wouldn't get too wrapped up about it.
FYI, I am not a lawyer or have never played one on TV.
