We are just a year into our 2013 3200 and we use it about once a month, so far just a few minor issues that were handled by the dealer. They were plumbing issues no hot water due to the check valve installed back wards.
So far no problems with the slides or the 6 point leveling system ( I really like the auto leveling) .
I had a Raptor before this trailer and a Weekend Warrior before that all have served me well. They all had their minor issues but I have found that I could fix most things myself better than the dealer hack.
Don't get hung up on the brand they all come from the same part stock pile for the most part just assembled in different places.
