Welcome!
Parkliner is the only one I know with a true 60" queen and bunks. It is a crossways, crawl-over queen. The lower bunk is pretty tight, but they do advertise the bunks as being able to support adults. It is currently being redesigned, but I am hearing there will still be a bunk option.
Escape doesn't have exactly the combination you want, but it does offer several options that sleep four.
A
Bigfoot 25RQ has a walk-around queen and a dinette that sleeps 2 more.
If you don't need a bathroom, a
Casita Liberty standard has a king-sized bed and front bunks.
For the most part, molded
fiberglass trailers are shorter and narrower than conventional trailers, so smaller beds are the norm. It's tight, but we sleep 4 in a 13'
Scamp. Two in a 45"x76" "double" bed (sleeping in opposite directions) and two more on 24"x76" bunks.
Best wishes figuring out what will work for you. Visiting a
rally is one way to get started. You will see a lot of different makes and models in one place.
