Welcome to the forum! Great advice so far. I would add, check the towing capacity of the vehicle you are planning to use to pull your new trailer. Then deduct extra for all the "stuff" you will be taking along, including people, water and LP gas. It can easily add to several hundred pounds.
We see a lot of overloaded SUVs and pickups out there. It's a recipe for disaster, and maybe a lawsuit later. That floor plan you like with the big slide might require a bigger tow vehicle. Happy shopping!
I think we need to stop calling it "working from home" and start calling it "living at work!"
