Earlier this year, we transitioned to a shorter 5th wheel from a smaller travel trailer. We now have a Winnebago Minnie Plus 27RLTS which is just under 30 ft. There are two opposing slides in the living area -- one for the kitchen and one for the sofa. The door is mid-coach and, like was mentioned above, allows full access to bathroom/bedroom. The living/kitchen area is less accessible than I would like with the slides closed (but obviously not a deal breaker since we now own it). The floor plan includes a kitchen island which blocks the refrigerator door when the kitchen slide is retracted in. If they had made that island only about 3 inches shorter, we would be able to fully open the fridge door. If we really needed to, we can partially open the slide to open the fridge and even scoot ourselves back to the dinette if we wanted to sit there.
So far, we have found this trailer/floorplan to be very functional for our needs.
