Can't help you with that model....believe it's brand new this year or last and no mention of anyone else with one. We have the Rockwood Ultra Lite 2604 and can tell you that we're pleased with it, the fit and finish, the quality. This is our second Rockwood, with the ROO 23SS hybrid being the first and never problem #1.
Since this is my first look at this model, I'll tell you what I see that would be good or not so good features for us. The garden shower is wonderful as are most of their new bathrooms - a huge improvement over our hybrid....the newer bathrooms usually have nice storage. The dinette is the standard style but larger than we had in our ROO and is a lot more comfortable....you can seat 4 for a meal lots easier with the expanded size. I'm assuming that the sofa has the air mattress that we have in our 2604 and according to those who've overnighted with us have said it was very comfortable - has a built in electric air pump and a manual one in addition. Quick and easy to set up....less than 5 minutes. The entertainment center is in a good location related to the sofa.
In the "we don't care either way" list is the outdoor kitchen. They are becoming very popular and those who have them are pleased. We would prefer to have that space indoors instead. We would choose no on that option, but don't see it as a negative. One of those to each his own things.
The island is a positive and lots of good living area opened up. The kitchen countertop by the stove is a bit shy, but I was spoiled with our ROO and the huge kitchen countertop...I miss it in our 2604, but what we have is functional and we've just learned to work differently.
The bedroom wardrobe set up is likely pretty much the same as ours and likely underbed storage and 3 drawers at the foot of the bed. While the wardrobes aren't huge, you can easily get a week's worth of clothes in each side - unless you're thinking heavy, bunky winter things.
Now the negative or not-so-good....I would not want to walk the length of the trailer to get from the bedroom to the bathroom. Our 2604 has the bathroom adjoining with a sliding door and was probably THE deciding factor. Realizing 27' is not miles, at the times we have had guests, it was nice to be able to have the sliding door between the bedroom/bathroom and a standard door between the living area and bathroom.....gave more privacy. Depending on how good these friends or family are, getting from the bedroom past those using the sofa bed could be uncomfortable. That may or may not have any effect in the way you camp and guests vs no guests.
Weightwise, the 2607a is a bit heavier, but pretty close...we're 5585/6629. We tow with an '03 F150 crew cab with 5.4 and factory tow. With our ROO we had an Equalizer and it did a fine job....other than the noise factor and it seemed DH always ended up dirty from handling it. The bars were too heavy for me to lift, so hook up would have been a major problem if I had to do it. The dealer suggested we look at the Blue Ox 1000. Their website has 2 good videos and DH liked what he saw. Shhhhh, nice and quiet. If needed, I could set it up - would rather not, but I could. Something you might look at if you haven't made that decision yet. Tows very, very well.
So that's the good and the not-as-good. We are very happy in this size range...still easy to fit most anywhere. Regardless the brand, you'll find folks that love it or hate it, but we've not anything that would make us unhappy with our Rockwoods. Good luck, looks like a nice trailer. Happy camping!
