Cat C7 350 in a Winnebago Journey

I am looking at possibly buying what I think is a late build '04 Journey 39K with 3 slides and a Cat C7 350 with 45,000 mi. The reason I say late build '04 is because I can't find specs on an '04 that match this motorhome but can find '05's that match. The owner says it's an '04. I have read a lot about this motor and it seems the HEUI fuel injection sytem can be very problematic. I have also read where owners say don't worry about that motor if you like the coach buy it. We really like the looks and the floor plan on it. Is this one I should stay away from because of the motor ?
  • Unloaded Vehicle Weight. The GVW on a 2004 Journey 39k is only 27,900 so it would be nice to know how much cargo you can load in it. My 2001 Adventurer 35u(which I just sold)had a chart with it that had the unloaded weight on it. We owned that coach for over 12yrs and had very good luck with it. Very well built. Never had to replace anyplace but tires. Oh, did replace bedroom slide hoses but that was due to HWH defective hose ends.

    Your spec placard, that's attached to the wall, right alongside the drivers seat, tells you all the specs for your coach. You say its GVWR is 27,900, well, it's actually 27,910. Your rear GAWR is or should be, 17,500. Your front GAWR is 10,410. So, together, you're looking at 27,910.

    As for your UNLOADED VEHICLE WEIGHT, well, that's easy, go weigh it. Put what you normally carry in it in terms of fuel, water, tools, chairs, equipment, and any supplies that you'd normally travel with and go weigh it. You'll come up with a figure that you'll either subtract from the GVWR or, you'll be very close to that GVWR or, possibly be OVER the GVWR. I've been over on mine quite a few times. Still rolling down the road.

  • I don't have the motorhome yet. We are going to look at it hopefully Saturday and I will see what it is then.
  • Maintenance, Maintenance, Maintenance. I purchased our Phaeton with 41k C7 CAT 350. I changed ALL the fluids, belts, shocks, gen maintenance, etc. No records from previous owners. I had CAT do the valve adjustment. CAT says at 30k, then again at 100K. I only use 5/40W Rotella and CAT filters. It's been a good engine for us, now with 64K.

    Good luck ;)
  • Here's a thread (over on iRV2.com) describing this filter mod: HEUI Pump Failures

    It can't prevent a problem with the HEUI pump, but it does protect the the fuel rail and injectors if a problem does occur with the pump--thus limiting the repair cost considerably. Although I've not had any problems at all myself, I'm certainly considering this for the C7 in my 2005 Vectra as extra protection.
