If you stay with the Nissan as a tow vehicle you are limited to low profile, single axle trailers. If the trailer you are considering has 4 wheels walk away.
On the other hand, if you are considering replacing your Nissan for a more capable tow vehicle look at all trailers. Find the one that works for you and then match it to an appropriate tow vehicle.
Also keep in mind that a small, lifted low profile trailer is easier to get into those hard to get to, out of the way wilderness locations. Plus you will have remaining payload for extra water, equipment, generator, fuel, etc. You have a 4WD Nissan so a small teardrop will get you where you want to go. I know I keep pushing Casita's but those things are bullet proof relatively speaking.
Don't give up. Your trailer is out there but it may take some time to find that ideal match for both your needs and vehicle.
