Gjac,
We have an '04 Itasca Horizon 36GD with the C-7 330HP CAT. It's an outstanding coach. It's very close in lots of ways to the 34H Journey other than its an Itasca. The fit and finish is great quality. Some worry about owning a CAT equipped coach. Well, first off, they don't break any more often than any Cummins does or, any Detroit for that matter (operated Detroits on the FD for over 30 years).
The "roof" thing is not as big a deal as some make it. Ours was 11 years old before the roof-to-gutter seals even showed signs of degradation. And even then, it was only a few feet from the front cap.
So, I removed all the old caulking/adhesive and, installed some new stuff. DONE! That was two years ago and it's been fine ever since. NO TAPE, just the correct SILICONE that was advised by folks that work on Winnes and Itascas for a living.
Anyway, we've now owned the coach for 6 years and have put 45K on the clock. Any coach will need SOME work every now and then. Some more, some less. I do all my own maintenance, inspections, brake work and more. And, speaking of brakes, ours has over 72K on the clock and the brakes are still at or above 80% or more. I don't expect to have to do any brake work for the full time of ownership.
The Journey and the Meridian are a very well known and purchased coach. I have many friends with both.
