I like it! Bedroom is essentially the same as in our Rockwood Ultra Lite 2604 but with both wardrobes shorter....you'll have plenty of room for hanging clothes or adding shelves of some sort and having folding space. Couldn't tell, but our 2604 has a lift up for storage under the foot of the bed....laundry basket fits perfectly in there with room to store linens. Very nice counterspace in the kitchen...more than in some of the larger units. Sofa with table for eating is no problem. Good TV location....watching either from the bed or sofa. Bathroom is like our ROO 23SS HTT....not fancy, but functional and we were fine with it for 8 seasons. You'll be glad you have that slide....makes everyone more comfortable and when the weather gets nasty you still have room to move without tripping all over. You have sufficient interior storage space if you think it through and bring what you actually need and USE and leave the rest home until you do. Think LIGHT!
I am by no means able to give you detailed towing specs, but would guess you're fine with a WDH/sway and the brake controller...required by law and common sense.
We're on our 2nd Rockwood trailer and have had no issues with either. Fit and finish were good, routine maintenance is crucial with any trailer. When we decided to move from our wonderful HTT to a TT, there was no question that it would be a Rockwood and the Ultra Lite 2604 is perfect for us.
Personal opinion here....we didn't care for the curtains in our 23SS and made a stop at Lowe's where they custom cut mini-blinds for the windows....you still have to do the top to bottom fit, but not hard at all, instructions were included. We kept the valances, but ditched the curtains and we felt it gave it a more upscale look and also seemed to make it feel more spacious inside. Around a $50 mod for the 2 windows, but well worth it for us.
