    AI summary

    The Forest River Berkshire XLT 45B is built around a Freightliner XCR raised-rail chassis with a Cummins ISL 450HP diesel and Allison 3000MH six-speed transmission, so it hauls a toad confidently on a 15,000-lb rated hitch. The multi-slide layout accommodates up to six and includes a full bath, while the full-height pass-through basement gives serious room for gear. Up front, the one-piece fiberglass roof, vacuum-bonded sidewalls, and dual-pane frameless windows reflect a construction approach that goes beyond the basics for this price tier. Optional upgrades like a stackable washer and dryer, stainless dishwasher, and basement freezer let you dial in the Berkshire XLT 45B to suit longer trips where home comforts matter.
