Welcome to iRV2.
The RV dealer will get a kick back for selling you an extended plan at your time of purchase , that kick back is part of the price he'll charge .
These things may happen .
Selling dealer will call you after you take delivery and offer same plan cheaper .
Or By calling around to different companies , you can get better coverage at a lower price.
Or, you can negotiate price on the the package; with the dealer; don't be afraid to make them an offer .
BTW, During my negotiations , dealer reduced extended protection plan price, on my used coach by 50%
