Description

Forest River No Boundaries 18 Series travel trailer NB18.3 highlights:

Queen Bed
Full Rear Bath
Outside Kitchen
Central Vacuum
Single Slide Out

This spacious trailer is perfect for weekend trips to the lake! Once you're set up at camp, put out the patio awning, make lunch on the outside kitchen, and grab your camp chairs from the slam latch cargo doors with pass-thru lighting. A jackknife sofa slide inside will provide more space and a place to relax in the evenings, and a full bath means you won't have to use the camp's facilities. The kitchen includes a cooktop and microwave, plus a refrigerator and overhead cabinets for food storage. When it's time to call it a night, the front queen bed is sure to bring comfort!

The Forest River No Boundaries travel trailers are exceptionally lightweight and can be towed by 4-cylinder and 6-cylinder tow vehicles! They are perfect for the outdoor enthusiast, and you'll find plenty of storage for your camp gear, personal belongings, and more! Each model is constructed with a welded aluminum structure, Azdel composite panels and a fully walkable PVC roof for added durability. There are a wide variety of floorplans to choose from, including 10 Series (under 2,500 lbs.), 18 and 19 Series (under 5,000 lbs.), plus 20 Series (under 5,500 lbs.). There's no boundaries when camping in these travel trailers!
