More protection than an LLC ???

[John M.]

I'm curious what everyone does to protect themselves from lawsuit when investing in rental properties.
I see that just about everyone does an LLC, but looking around on the internet, I also see people talking about things like: Irrevocable trusts, living trusts, and doing your LLC in states like Nevada, Delaware or Wyoming where the laws favor LLC owners.

Does anyone here do anything beyond just an LLC + Umbrella Insurance?
Any advise/recommendations?
