Our '08 Trail Cruiser Hybrid C191 had very few issues. Had to replace the tires, that was it. Other than typical hybrid trailer things, a very trouble free trailer. Had a nice build quality, good appliances.
Our 2014 Wildwood 261BHXL has been trouble-free so far. Loose shower hose, that's been it. Love the floorplan. Compared to the Trail Cruiser, I don't think it has the build quality. Don't get me wrong, it's a nice trailer. But the fit and finish is a little under the older unit.
I also like the Norcold fridge that was in my precious trailer better than the Dometic.
We love our trailer, hope we can continue to enjoy it for many years.
As for vehicles, when we bought Chrysler products, they were constant problems. After switching to Honda and Toyota, we haven't been back to the dealers except for maintenance.
