If you are restricting yourself to something less than 3,500 pounds fully loaded, then I would keep looking at the A-frame A-Liner type of travel trailer. They fold up, and are very compact, to meet the 3,500 pound tow limit of your current vehicle.
I would not bother with a toilet, because they are so small, and further recommend camping only in a campground with a toilet facility nearby. Many private campgrounds have this, so do most Federal campgrounds that allow tents. Like Zion NP has a area for tents, and pay showers. They do get shut off in October, before any freezing weather hits, and do not open until spring. But if you are restricting yourself to less than 3,500 pounds, it sort of prevents space for a full size bathroom.
If you are willing to trade up to a truck or Expedition, then you can tow much more, like 5,000 - 8,500 pounds. A Lance trailer is very well built, and will last many years. But that runs into restrictions for your parking area.
There are a lot of choices out there. Personally, I do not think I would like the sleeping arrangements in a teardrop. I am to tall, and like to stand up in the morning. I like my buddy's A-Frame A-Liner RV. But still it is a bit on the short length wise. I would rather see them build a 22' long unit, with more space dedicated to full bathroom.
Right now I have a 30' Bounder with a huge bathroom. The queen bed is in the back, in front of that is the bath with shower on the drivers side, toilet towards the middle, and two doors. This can both be closed, or both open to block off the hallway, and give a private dressing area. The sink and closet are on the passenger side. So a total of 6 feet X 8' wide is dedicated to the bathroom. Just about right sized for my liking!
If you do not want to trade the Jeep, you might consider a 22 - 25' long class C. While insurance is a bit more for the class C than a trailer, they are easy to park, have a much larger fresh and grey and black water tank in them. You might be surprised that you could park one in your driveway. Also you can call the insurance agent, and say it will be parked. Leave the fire insurance on it, but stop the most expensive part, liability.
Good luck, and have fun camping!
Fred.
