I started out thinking I would get a USED RV but a friend insisted I look at new ones. Well, today I found a new FX-21 QB Freedom Express by Coachman and the salesperson mentioined 'its on special', 'We can throw coupons at it to save $13000 off retail', ' If you wait, you won't be able to get the discount soon'. I was told I can buy the mentioned RV for $49K. Is it acceptable to make an offer below the asking price, similar to a car purchase? If an offer is acceptable, how much can I expect to save from the list price?
