MONTANA 3721RL 3721RL
**Price Reduced For Quick Sale**. All reasonable offers considered. <br>We purchased this "4 Season & Residential Living Package" camper to live in in Florida when we retired. We actually only got to "live" in it 3 weeks as we were blessed with the arrival of our first grandchild. Grandma then decided she couldn't stay away. However, this camper is the perfect size and roomy enough for a couple to live in! It will sleep 4. We thoroughly enjoyed living in it during our short 3 weeks. Since then, we have used it 3-5 times each summer at state parks close to home. The camper is exceptionally clean and has been well maintained. The setup is quick & easy due to the automatic leveling system and front/rear power leveling jacks. It has 3 slides, 2 awnings that span 19 ft., prewiring for tv antenna, cable, washer/dryer hookup, microwave/convection oven, 2 propane tanks, interior/exterior speakers, outdoor TV, 2 interior TV's, fireplace, central vacuum cleaner, residential refrigerator (it’s huge!) w/ice maker, upgraded sleep number mattress on king bed, dual whisper quiet A/C (very quiet if you’re familiar with how noisy the A/C can be), generator ready, tons of storage space (inside & out), upgraded heavy duty high ply Goodyear tires, and two new batteries (purchased 5-21-23). All the manufacturing kinks have been worked out and is ready to use!  Will also throw in bike rack that holds 2 bikes.
