2004 Winnebago Horizon Itasca Drivetrain Question

Hello all,

Quick question for noob looking for a full-time live aboard coach.

Going to look at a 2004 Horizon Itasca 40QD and it has a 400hp badge (see attached) on it but the brochure says they only made a 330hp Cat and 350hp Cummins. Was it a factory option or maybe a reflash?
https://library.rvusa.com/brochure/04Horizonbro.pdf

Also, noticed a "TTT' badge on it also, is this another option?

Anything else to keep an eye out for on this vintage and model of motorcoach besides the normal stuff you have shared in the stickies for the noobs?

Thanks in advance.

Jeff

My guess is that a previous owner has added some aftermarket parts to increase the horsepower.

Thanks, is there a way to tell from the VIN the engine model and if it has IFS?

If you have the VIN, Freightliner can tell you if it IFS but the easiest way to find out is look under the front end.

Could it be that what you think is TTT is an M with possibly wings. I couldn't tell what it means but just saying.

Just found out it has the Cummins 400 HP 8.9 ISL as a factory option from the sticker.

Does that mean it will have IFS then also? Looks to be nicely optioned.

Brochure was printed before the model year and distributed to sales dealers .

So the 400 HP might be a running production model change . As mentioned a call to Freightliner or a good close look at the engine data tag will clear things up.

A quick look at the 2005 brochure might shed some light on the matter . See if 400 HP was standard or option.

BTW : Freightliner completely changed the wiring harness and dash gauge package , on Jan 04, 1999 . So coaches built from Aug 1998 to Dec 1998 have a completely different wiring that those built at the end of the production year , even though all are 1999 coaches .

EDIT: I see a post came in while I was typing , sorry if this info doesn't help.

Not sure , if you have access to the coach look on the wall to the left of the drivers seat for a production tag from Freightliner . If the tax says " XC Chassis " then it's not IFS .

Now this is a sure sign that I'm getting old and forgetful , two years ago I was under the front end of a friends Winnebago on Evolution chassis , working on a slide hydraulic leak ; and I simply can't remember if it was IFS and I can't find Evolution mentioned on the FCCC web site.

I'll do some more searching .

EDIT : Back in time to add this , Evolution appears to be a variant of the XC chassis and has an ZF , IFS option .
Can't say for sure if Winnebago made it standard . YET.

Cool, thanks for digging.

I hope to go drive up north to check it out next weekend and will report back.

I got to the Winnebago site for brochures and the, 2004 Horizon, listing shows the Evolution chassis as " optional " even on the 40' coaches, and the PDF I posted earlier doesn't say IFS is standard on Evolution chassis, so right at the moment , it appears that having a look under the coach for the IFS , is the only true way to confirm front suspension.

The 'Built On Freightliner' info the 2004 Itasca Horizon lists the CAT C7 with I-Beam front axle as standard and the Cummins with IFS as optional. (They also list the Cummins as 350HP, but presumably the 400HP was a later upgrade.)
