To the OP. I applaud you on doing your research. If you go over to IRV2 in the Palazzo forums you will see a lot of satisfied owners. I really, really feel like mine and the few other owners who have had massive slide out issues were the Guinna pigs for the Schwintek issues and consequent fixes.
I took a little poll over there and I came up with a 29% failure rate. You can search the posts and see for yourself. If you can stomach a 29% failure rate then by all means take a look at a Palazzo. Mine is fixed for now. I am keeping it. It does not give me comfort in knowing it could self destruct again at any given time.
