"IMO substandard RV products are offerred because we can't afford to pay for the good stuff"....trust me, there is not much distinction between the workmanship of entry level rigs and the "good stuff"...unless you really get into the high end market of the top 2-3 manufacturers.
IMO, the reason poor quality rigs are pushed off of the assembly line is that there is no motivation to do otherwise. Obviously there is enough markup in the sale price to cover the anticipated warranty work, and there are enough new people standing in line to purchase their product...so why change ?
