You are going to need to size the trailer to your tow vehicle if you have a TV you are planning to use.
Whatever TV you have selected it will need a tow package. There are several things a tow package has but most importantly it has a transmission cooler and brake controller.
You are still going to need to focus on GVWR and other factors. You want to avoid front wheel drive vehicles.
As you will be on unimproved surfaces 4WD will be essential unless you are looking for frequent tows.
You also need to mention what you are willing to spend. Does it need to be new, or are you willing to go used while be aware a trailer can hide serious problems even from the experienced.
Mission creep can be a real problem. Smaller lighter generally means better MPG. BUT smaller might be much more trying.
Pop-ups can be nice but you have to clear everything off the counter tops before you close up. It also means more setup time and when you are time taking an hour to setup can be exhausting.
You need to decide how you are going to work in your trailer. Is there enough room to work?
