I had no idea Fiat made RVs.
My wife had a Fiat 500 (very much not an RV). It lasted (with minimal maintenance other than oil changes, tire replacement and one set of struts) for maybe 8 years before we sold it to a friend of ours and it's still going strong (maybe 11-12 years old).
That said, I've had a number of Moto Guzzis and Ducatis and Italian engineering is... idiosyncratic. I did most of the wrenching on those. Loved the handling, though. I had a track-only race bike but I had these on the track sometimes as well and could get lap times withing a few seconds (disclaimer: I was either the fastest of the slow guys or the slowest of the fast guys. Nothing special, but I was having a great time out there.)
