The interesting part is when an RV owner has valid complaints about quality and engineering, many choose to side with the manufacturer and criticize the buyer for the audacity to complain. Either the manufacturers are moles on the various forums or the those who stick up for the manufacturers are less than intelligent.
BTY proper engineering and QC does not need to cost more money. In fact poor engineering and QC does cost more money if one cares to consider warranty costs and loss of business.
