RV Description

This camper has been exceptionally well cared for, meticulously maintained, and is in fantastic condition inside and out. As the original owners, we've made wonderful family memories with it and hope its next owners will enjoy it just as much as we have!

The 3660MB is a fantastic floorplan with four slide-outs, offering plenty of living space and flexibility for families or couples who enjoy having extra room.

Highlights include:

Private master bedroom

Separate mid-room, perfect for kids, guests, or a multipurpose space, such as an office

Additional loft area for sleeping or storage

Spacious rear living area with comfortable seating and entertainment space

Large kitchen with island, plenty of cabinetry, and generous counter space

Dining area and ample storage throughout

Outdoor awning, outdoor lighting, exterior storage compartments

After-market airbag/shock pin box

Customized Mid-Room: We made one modification to the original floorplan: we removed the sofa bed in the mid-bunk slide-out and replaced it with a twin bed and shelf. This creates a comfortable, dedicated sleeping space with additional storage. The loft above provides even more flexibility for sleeping or storing belongings. We still have the bunk should you wish to add back in the second bed.

Exceptionally Well Maintained: We have been very diligent about taking care of this camper, both cosmetically and mechanically. Maintenance has always been a priority, and we've consistently taken care of the little things to keep everything in excellent condition.

Roof and seals inspected and conditioned annually

Always properly winterized

Kept covered when not in use RV cover included with the sale!

New tires, with spares, within the past year (less than 400 miles)

Exterior and awning regularly cleaned and maintained, very minimal normal staining

No black streaks or unsightly exterior buildup

Interior kept exceptionally clean and in fantastic condition

Regular preventative maintenance, including checking and tightening components as needed

No known mechanical or functional issues everything works as it should!

Gently Used and Well Loved

We've primarily used this camper for a few local (within 30-100 miles) camping trips each year, along with one wonderful family trip to Disney. It has not been used for full-time living or constant travel.

We have always taken pride in keeping it clean, protected, and properly maintained. It really is a beautiful camper, and we've put a lot of care into preserving its condition.

Why We're Selling: We're simply camping and traveling less these days and have decided it's time to downsize. There are no issues prompting the sale our family's needs have just changed.

If you're looking for a spacious, comfortable fifth wheel that has been genuinely well-cared for, this is a wonderful opportunity. We know buying a used RV is a big decision, and we're happy to answer questions about its condition, maintenance, and features.

Additional items will be included i.e. water and sewer hoses, wheel locks, cover

Serious inquiries welcome! We'd love to see this camper go to another family who will enjoy making memories in it!
