With the slides in, all beds are accessible; however, you cannot pass through from the front to rear of the trailer. Because there is a back door, you can have access to the bunks and bathroom. The kitchen is not accessible, though there is the outdoor kitchen.
What we love about this trailer is:
Amount to storage (big pantry, cubby holes by queen beds and under bunks, large drawers in dinette)
Layout (second slide is a game changer in terms of roominess)
Rear door into bathroom
Quality of construction seems better than some we looked at (not perfect though)
Large awning runs entire length of trailer
Friction hinges on entry doors (we have small boys and it has saved their fingers more than once already, though they have a tough time opening the doors)
Magnetic latches on pass-throughs and outdoor kitchen (makes them idiot proof)
Pocket doors separating the bedroom from the rest of the trailer
A lot of this is not unique to this trailer, but to have all of these in one unit at this length was harder to find. It seems like they thought of a lot of the little things and convenience items included them standard. There were actually not many "options" you could add.
Things we don't love:
There is honestly not much that we have found and don't like, very minor things
Outdoor kitchen is smaller than some, but still very functional
The, i'll call them reading lights for a lack of better term, are too bright above the queen. I'll have to find a way to dim them down
After a few uses we have seen some wear and tear. All on trim/cosmetic features and granted we have had 2 small boys + their cousins "playing" in there
I will be upgrading the TV mount with a swivel type for better view-ability
It would be nice if the top bunk had a higher weight allowance. It is 200 lbs and works for kids but is iffy for most adults.
I am struggling to come up with things that don't seem too nit-picky
All in all we absolutely love this trailer. It works great for our family of 4 with 2 young boys. There is plenty of room to even have a guest couple. The length and weight make it easy to pull and park.
Obviously everyone has different things that they consider must haves or deal breakers. This one had the most must haves for us and I feel like the only thing we compromised on was the size of the outdoor kitchen (there are some that have an undercounter size fridge and larger opening out there, but not many in the size trailer we were looking for). If you have any other specific questions, I can try to answer; however, we have found that just because you see something on one trailer, doesn't mean it will be the same on yours.
Hope this helped and good luck.
