One thing to consider, no matter who makes it, all of them get the components from the same suppliers, and all of them hire from the human race. So the fridge, axels, AC, etc. will all have the same success/fail rate. As humans, we all make mistakes, and have good & bad days. Personally I feel that where RV manufactures are dropping the ball is that (at least as far as I know), most or all of them have a quota of rigs they want built in a day. When they have met their quota for the day, the employees can go home. No matter if it's noon, or 6:00, so naturally everyone one wants to go home early, so they are rushing to get things done, in the rush, something may be accidentally overlooked, or intentionally overlooked so everyone could leave early.
