We have a 38 foot with a 14 foot long X 4 feet deep slide out in the living area and a bedroom slide out. The other model we were looking at was the 35 foot 5th wheel by the same manufacturer. By going to the 38 footer it provided a dedicated closet for a stackable washer/dryer and a foot deep counter at the rear in the kitchen area plus cabinet beneath.
It is a perfect unit for fulltiming. No bottleneck areas, plenty of storage, great heat & A/C plus other amenities.
We have added some items to meet our needs- Replaced the dining table with a combination dining table and desk. We also added an electric fireplace/space heater for ambiance.
We have enough floor space in the living area that we set the dining table and chairs in the middle of the floor which provides great access to the desk area.
We can also place one of the recliners out in the floor and still have room to walk around comfortably.
It's amazing what the extra 3 feet provided towards a more comfortable RV.
