New 2026 Keystone Carbon 358 — Tulsa, OK

The 2026 Carbon 358 is Keystone's toy hauler on the Bunkhouse floor plan. This one is new and listed at $53,855. Dry weight is 13,271 lb, well above the 8,704 lb median for the category. At 38 ft 11 in it is slightly longer than the category median (35 ft 7 in).

Expect roughly 15,650 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.

Sleeping capacity is 8 — more than the 6 typical of the category. 3 slide-outs widen the interior considerably at camp.

That is a 37% reduction on the $86,099 MSRP — $32,244 off. It sits above the $38,249 category median, reflecting its size and specification. We have flagged it as a great deal against comparable listings.

Fitted equipment includes electric beds w/ dual opposing couches, 6-pt hydraulic auto leveling, rvia and solar flex protect. It ships from Tulsa, OK door-to-door to any of the 50 states, inspected before it leaves, at one transparent price with no dealer fees.
