About the price: Builder's "MSRP Starting At" figure for the 45CB floorplan, as posted on dynamaxcorp.com on 5 October 2026. Dynamax says it is the base price of a standard-built coach and leaves out tax, license, registration, freight, options, and dealer prep and fees.
These values describe this model year and configuration. An individual coach can differ, so check it against the coach’s own records. “Not documented” means the encyclopedia does not have that fact yet.

Notes
GVWR 58,000 lb; GCWR 80,000 lb; front axle rating 18,000 lb and rear tandem 40,000 lb. Wheelbase 349 inches. Hitch rated 32,000 lb with a ball or 40,000 lb with a pintle, with a 6,000 lb tongue rating. Awnings 21 feet and 12 feet 6 inches. The floorplan page gives no usable LP-gas capacity, so none is recorded. The brochure carries the print code 08/26. Only one floorplan is offered, so every value here describes the 45CB.
