We purchased this Momentum in August 2024 from Texas. We lived in it this past year over the winter in Utah and moved back home to Wisconsin in May 2025. We are purchasing a home and no longer need it, it was great for our family and used the garage only as a bedroom for our two daughters. The garage also has washer and dryer hookups.
