The sad thing is they try to do everything the cheapest way to get them done.
The dealers and the buyers then have the usual bickering to try to resolve issues.
Lots of money changes hands and the buyer gets stuck having to either wait for repairs to be scheduled or drop off their new unit for it to sit for weeks or months to be repaired.
I bought a 2001 Beaver 3 years ago and have had some issues, but I expected to have some things to do.
When you spend the money to buy new you should not have a whole list of stuff to have fixed. Once the dealers get the Rv's they should do a better job checking them over before offering them to a customer.
If things need fixed it should be done before the customer drives their "new" coach off the lot!
