I worked on construction equipment for over 40 years the 15 as service manager. Be for that farm machinery. Never did I work for a company that put things out for sale that wasn't ready to sell. New units got a PDI and used units were made ready be for they were sold.
I have had RV salesman tell me that if I buy it they will check it over and fix what's wrong. Why would anyone go along with that. If a new unit needs work before it should be sold they should not sell it.
Many dealers have good RVs in the lot ready to sell, people should go there.
Yes I have seen good camping world stores.
