Welcome!
First lesson is to ignore the dry weight. It is a fictional number. No one tows a trailer at it's dry weight. Dry weight does not include factory installed options like AC, awning, oven, or even the spare tire as is the case with some manufacturers. There is a yellow sticker on the driver side of the trailer that lists the "shipped" weight, which is always higher than the advertised dry weight.
A better planning number is the GVWR. That's the allowed total weight of the trailer fully packed and ready to camp in. Most of us don't fill them to that extent, however the real tow ready weight most of us have is closer to the GVWR than the dry weight. Hence it's a good number for planning.
That said, what are you towing with? What is the payload (on a sticker in your driver side door jamb)? With that info we can make a better determination of what's realistic for you to tow, and that will help narrow down your research.
This is important because far too often people buy a trailer that's within their listed towing capacity but will easily push them over their listed payload. Towing capacity is not a hard and fast number. Knowing your payload and tongue weight limit need to be factored in as well.
EDIT: The
Jayco Jay Feather SLX 18srb may fit your requirements very nicely.
EDIT again: Oop, sorry. I didn't catch that you need 2 bunks also.
