After 10 years of going to RV shows and studying the issue of what kind of RV to get, we bought a 2016 Jay Feather 23MB in January of '16. Absolutely no regrets.
I think the size and weight (about 4800 lbs dry) are right for a standard full-size gas truck. I have a 2012 Ram 1500 5.7 liter V-8. Last year we pulled it 7,000 miles, including one trip of 5,000 miles towed over six weeks.
IMO, the Murphy bed is the best idea for live-ability since the slide out was invented. We have the sofa and dinette, and nice open floor space. (Get a "folding ottoman" to use as a place to put your feet when sitting on the sofa).
The MB option makes our 23'(box length) trailer as roomy as 28-30 footers with fixed beds. In talking with salespeople and also my observation at RV shows, people either love or hate the MB idea. after approx 8 weeks of using ours, we love it. It is very quick and easy to put it up and down. BTW, we are 65/68 years old, so athleticism is not required! We usually put it up as soon as we get up, but if we plan to be gone all day, leaving it down only takes away the sofa, there's still plenty of floor space left and the bed doesn't restrict access to the kitchen, storage, TV, etc.
Not sure why you are averse to the dinette, but the one in our model is nice - it seems the right size, and the table is not fixed. We slide it around to fit the situation of the moment - more leg room at one end than the other, accommodating more people, etc.
This is off the subject, but another big issue to consider is kitchen configuration/countertop space. Many designs just don't have any counter space, which is probably okay if you don't plan to cook inside very much. If you plan to spend a week or two (or more) vs. weekend use I recommend giving this a lot of thought.
Last thing, our model has lots of storage, more than we need actually. Again, for weekend use, this is a different concern.
