We own a 2015 Dutch Star 4381, although a few differences between the DS and Ventana line, the floor plan is almost identical.
We're very pleased with the functionality of this floor plan, works well for us. I was not interested in a full wall slide and we wanted a bath and a half so this was one of the few plans available with these features. Another preference for us was the dining table on the door side of the coach, we really wanted to be able to look out over our own patio area as opposed to our neighbor's site. Additionally, we had Newmar move the televator TV from the DS of the coach to the ODS so we could leave that window open to a view of our patio.
This floor plan has far more livability with the slides closed than a floor plan with a full wall slide. We also ordered the standard dinette so that we could maintain as much space as possible between the dining table and the kitchen with the slides closed. Another thing we like about this floor plan is that if we overnight without deploying slides, we can still access the main bath and shower without having to crawl across the bed. The half bath in the 4381 is also larger than the half bath in any other floor plan so it's quite functional. We are also very pleased with the double vanity in the main bath.
The two bathrooms located mid coach also keeps most plumbing centrally located which reduces the length of plumbing runs with hot water to the fixtures very quickly (saves water when running off the tank). This was also a maintenance and repair issue for me, should be easier to repair problems and perform maintenance when it's all centrally located and above the tankage.
There is no obstruction of access to your wet bay, power bay or Oasis system with this floor plan with the slides deployed which I really like. But, on the flip side of that, because your kitchen is on the ODS of the coach, the front slide on the DS is the flush floor which reduces the height of your basement doors, which happen to be the ones you will probably access the most. This is the only drawback I have found with this floor plan but the many plusses easily make up for this.
I walked through a Ventana 4381 prior to ordering and assumed everything on the floor plans were identical. I was disappointed to discover that the pantry on Ventana is about 5" wider than the pantry in the Dutch Star, don't know why but the front DS slide on the Ventana is 5" longer. Wish we had that large Ventana style pantry!
In a nutshell, we love this floor plan and we're very pleased with the Newmar product, this is a great coach.
Send me a PM if you have any specific questions, more than happy to help with more information if you need it.
