2020 Keystone Montana 3855BR with 4-seasons package that includes heated water tanks and heated/insulated belly for year-round living! It has been barely towed as it was parked at a permanent covered site in Illinois when we bought it Feb 2022. We towed it to Colorado Springs and lived in it full-time Mar-Oct 2022 until we bought a house. We installed a stackable Splendide washer & dryer w/ exterior vent. We built a loft bed in the bonus room slide out for our daughter to have more room, but we still have the sofa bed if wanted. We also installed vinyl flooring in the loft for our son's bedroom area. Great floor plan for a family with tons of storage or use the bonus room as a home office for remote work! RV is in great shape except for a minor dent/blemish in the lower-rear passenger corner from the previous owner. Asking $66,000 OBO. USAA currently holds the lien.
