2004 Winnebago Journey WKP39K (30,370 Miles), Cummins 8.3L ISC (330 HP), Allison Transmission, Workhorse Chassis, 3 Slides, Custom Wrap
If youve been looking for a top-of-the-line diesel pusher with extremely low miles, a legendary drivetrain, and a much newer look, this 2004 Winnebago Journey WKP39K is a rare find.
This is not some stripped-down entry-level coach. It was a high-end model for 2004, and it still stands out today because of its quality, power, layout, ride comfort, storage, and overall presence.
This coach has been lightly used and is in terrific shape for the year. We just dont use it any more (our kids are older now so we will be down-sizing). Sleeps 5 adults comfortably & could host 4 adults w/ 3 kids utilizing ONLY the Coach beds (add a blow up mattress and you can get 5 kids / 4 adults.
This Winnie is powered by the highly sought-after 8.3L Cummins ISC diesel rated at 330 HP and 950 lb-ft of torque. This 8.3L Cummins ISC can be tuned to push out close to 400 HP if you need it. The 330 HP was more than enough for us and our toys (9,500 lbs. is what we towed). This engine alone is one of the main reasons this coach stands out. Paired with an Allison transmission on a Workhorse 6P chassis its unstoppable. The Roof was replaced in 2017 by previous owner (its a 1 piece roof which is why we bought it-NO ISSUES). The RV also has a custom exterior wrap that gives it a far newer, more modern appearance than other 04 RVs on the road.
Open the 3 slide-outs and you get a huge main living area along with a spacious, comfortable master bedroom w/ mirrored closets, making this coach a great fit for family travel, long road trips, extended vacations, or snowbird use.

Issues / Disclosure
Passenger-side front seat recliner lever is broken (still works - just snapped)
Windshield has a rock chip that has been sealed. No spider cracking. Windshield was expensive so I decided to wait / see if it would crack further before replacing
Front driver and passenger seatbelts work, but they can be fickle / not retract smoothly but I have new ones on order and can replace
This is a terrific RV that has been lightly used, she has the big Cummins 8.3L ISC, Allison transmission, Workhorse Chassis, and extremely low mileage. Generator is the BIG BOY (7.5KW), Solar Panels, Inverter, and the Lithium battery have been upgrade, extensive storage, a custom modern wrap, and strong maintenance history with all records and receipts included.
Why spend substantially more on a newer one when this coach gives you the drivetrain, ride quality, layout, storage, and overall presence that matter most? Youd be hard-pressed to find another coach with mileage this low, the sought-after 8.3L Cummins ISC, Allison transmission, Workhorse 6P chassis, and everything you need to get your family from site to site and vacation to vacation in comfort and confidence.
ISSUE WITH BUMPER; the rear bumper (during our last trip) came loose. Duct tape was introduced to "hold it on" LOL. I'll need to secure it but with work schedule and summertime w/ kids out it'll be hard. We can have discussions about this in person to accomodate this issue.
