Sometimes that seems to be the only way.
In my years of experience, I think that RVs, more than most other high cost items, are purchased based more on price than any other factor by the majority of the customers. Since quality control is something that costs the factory a lot of money with little or no return in the RV industry, few RV manufacturers have much of it until you get into the million dollar RV market where price is no consideration. I suspect that is partly due to the fact that the majority of RV sales are to people who will only use them occasionally and do not live in them much. The way that I see it, the poor quality of the majority is the fault of we buyers who are unwilling to pay what it costs to have effective quality control.
While that does happen at dealerships far more than it should and sometimes by the factory when a dealer tries to help it's customers. I have only rarely seen the person with an issue blamed for it on RV forums that I visit. I am also sure that there are incidents where a problem was caused by the RV owner, but doubt that it happens very often and when it does, that could have been caused by a poor walk-through by the dealer personnel. The best delivery walk-through I have had was at a dealership where it was done by the service department and they told customers to expect it to take about 3 hours.
