We had a few things right from the initial purchase but nothing major:
1) Electric portion of the water heater wasn't plugged in all the way (found on 2nd trip)
2) Main entry door latch needed adjustment
3) Loose screws attaching the bedroom floor structure in the pass-thru storage
4) Pass thru storage door adjustment
5) Black tank dump valve froze and had to be replaced. They said the routing of the cable was poor so they fixed that too...
6) There are a few fit and finish items as well but no worse than other trailers I've seen.
I'd say most, if not all of these are results of poor quality control in manufacturing/assembly, not product design.
The auto industry with all it's issues is light years ahead of the RV industry. Just looking at the "behind the scenes" routing of electrical was enough to convince me of that. I don't think it is unique to Winnebago, other friends with different brands have shared similar issues. Winnebago purchased Grand Design and pulled a lot of design and feature content from them for the Voyage series. We looked at GD but they didn't have the combination of features in the size trailer we wanted.
Overall we are happy, though. We love the size and layout. It pulls nicely behind the Tremor (7.3) and feels solid. The extra interior ceiling height is nice. We like the dual entry doors and were originally looking at the 2427 but are glad we went up a size. The extra interior space (both perceived and actual) is very noticable along with more interior light from the additional windows. Dual doors allow us to easily access the entire trailer with the slide in which is a nice convenience. Tons of storage - no issue there at all!!
We did not order ours - it was on the lot. The things I would have considered changing are:
1) The larger AC/propane fridge isn't necessary for us. The smaller fridge (at the time) was 12V and I think I would rather have that. Now I think it is the opposite and the larger is 12V so who knows...
2) I would have ordered the second AC unit although that can be added - it is already prepped
3) I would've ordered with the dual pane windows. We camped in the high 30s for several days last year and it did fine but would rather have the duals for efficiency and sound damping.
4) on a positive note I thought I wanted the auto leveling system but ours came with typical power stabilizers. Those work fine - glad I didn't get anything more high tech that may fail down the line.
We have the king bed, trifold sofa, dinette, and wouldn't change any of those.
A bit nit-picky but the TV is a nice size but isn't a "smart" TV so we had to hook up one of our Amazon fire sticks... honestly I didn't even realize they were making non-smart tvs.
Happy to see ours had 200W of solar factory installed as well as Goodyear Endurance tires. I think both of these are standard items now...
Let me know if you have any specific questions and I'll answer if I can!
