In your example from a Flair to a Bounder I think they come off the same line made by the same people and same production processes. I don't really believe the Bounder at $40k more uses better FG or stronger adhesives to prevent delamination, better chassis parts to improve the ride or better appliances. I think the difference in price would be things that the Flair doesn't have like a fireplace, outdoor TV or kitchen, full body paint etc. If these things are not that important to you I would rather get the Flair and put the money into fixing the Mfg's defects and customizing the MH the way I want it. Just because you pay $40k more for a MH doesn't mean you will have less problems to fix.
