Heartland Milestone fifth wheel 370FLMB highlights:

  • Middle Bunkhouse
  • Loft
  • Separate Living Area
  • Kitchen Island
  • Free-Standing Dinette
  • Theater Seats


A middle bunkhouse, a loft, a separate living area from the kitchen, and a master bedroom with plenty of storage will allow you to camp in luxury with your whole family in this Milestone fifth wheel! Beginning with the separate living area up front with dual opposing sofa slides, theater seats, and a front wall entertainment center, you can watch the big game and relax until the sun comes out. The separate kitchen area also offers dual slides for more floor space around the kitchen island which the cook will love. You will appreciate having your own walk-around pillowtop king-size bed, two wardrobes, and a door to close for privacy when the kids will not stop giggling in their own bunkhouse. They will get to choose from two bunks and loft area each night, plus the sofas in the living area offer extra sleeping space too.


The value-drive luxury, enduring structure, and aggressively low pricing is what will draw you in to the Heartland Milestone fifth wheel! The Milestone includes great innovation from Heartland, and it also comes standard with a 2" receiver hitch, painted front cap, and an X1 control system. The quad aluminum steps and friction-hinge 30" entrance doors enable you to enter your unit with ease, and the industry-leading exterior graphics will catch the attention of everyone you pass on the highway. You will receive superior ventilation from the massive tinted safety glass windows, and the anti-microbial solid-surface countertops in the kitchen are very clean and sanitary.
