I suggest you approach trailer selection more practically. The two most critical practical issues are, Where do you want to go and how much of the year are you prepared to lose to unavailability?'
All stock trailers are only strong enough to handle improved roads. For starters, there are ~185,000 miles of US Forest Service roads that stock trailers will self-destruct on. Further, you will be parking a 3 season trailer for 3-4 months per year or be driven south to avoid winter temperatures. A 4 season trailer is needed to avoid this loss of use. These two issues will dictate how much use you get from your trailer, its ultimate cost of operation and the comfort level you'll have.
As posted above, the under 2K weight is a tough requirement to meet with travel trailers. If you decide to not get a more capable TV, I would suggest looking at some pop-up campers. MANY of them are under 2,000 pounds. Get into the sport and over time upgrade to larger/heavier trailers as budget and your experience as to what is important develops. Good luck, and have fun!
Looking at that link, Armadillo make a solid little trailer with double walls for better insulation. If you want to go a smidge bigger, the company recently introduced the Backpack, which is 6” larger than the Armadillo. Those extra 6” are added forward of the door in the dinette/bunk area. Still under 2,000 pounds.
We looked around spoke to a retired Engineer who was very picky.
He told me line by line about Casita vs Escape (British Columbia)
We could not find a used Escape for under $23k
Ordered one for $25 it took a year ( probably quicker now with expanded production since 2018.
We love our 17’ escape
I have a 16-ft casita that has no bathroom and weighs 1,600 lb empty. Including my gear and the people and coolers in the car, I'm sure it is considerably more than that but must not approach my 3500 tow limit as it toast perfectly and is never hand my vehicle. I tow with a Ford Escape.
