We downsized from a 35' 5th wheel 3 slides to a ACE 29.3. Now that's not your 25.6 Vegas but close. The ACE had a full body slide, I had no problems with that as long as you follow the mfg guidelines. The main one is NEVER stop the in or out operation until the slide is in the full in or out position. Then you still have to push the button for the motors to sync. but again that's really not a problem. As for towing I towed a KIA on a dolly no problem. For me the ride was not bad, quality of workmanship so, so.
With all that being said we made a mistake and downsized (for uus) to much. We were not comfortable with it on long trips of 3+ weeks. It was great for a week or so. We ended up trading for a older, bigger coach.
