New 2025 Keystone Montana High Country 373RD — Oklahoma City, OK

This new 2025 Keystone Montana High Country 373RD is a fifth wheel on the Rear Entertainment floor plan, listed at $49,227. At 41 ft 4 in it is right around the median length for a fifth wheel (39 ft). Dry weight is 13,399 lb, above the 12,195 lb median for the category.

Expect roughly 15,800 lb once it is loaded for a trip. That calls for a one-ton pickup, ideally a dually, with 15–25% of that through the kingpin landing on the tow vehicle — this is firmly heavy-duty territory and the truck matters more than the trailer.

4 slide-outs widen the interior considerably at camp.

It is listed $43,660 below the $92,887 MSRP, a 47% saving. We have flagged it as a great deal against comparable listings.

Among its listed features are rvia, free standing dinette & chairs, solar flex protect and 2" accessory hitch. It ships from Oklahoma City, OK door-to-door to any of the 50 states, inspected before it leaves, at one transparent price with no dealer fees.
