Mine is a '02 Journey DL @ 36' and it's really well made. I would guess that one you're looking at is as well made as mine. Here's the brochure that might give you some insight to it's features that a mere ad often wouldn't...
'03 Journey
Note that any big machine like an RV is going to have problems, and an above comment is correct about looking at the roof carefully but Winnebago uses a 1 piece fiberglass roof so it's pretty good for a lot of years. I would also recommend looking underneath the rig to see if it's rusted out. If the PO lived up in the rust belt, I'd pass on it. Salted roads are not good on the undercarriage though a bit of rust isn't all that bad, too much is terrible.

Several items were due to lack of maintenance by the PO, other things just wore out, but the Journey is a well made, upper level RV in my opinion.
