you need to post what they want to charge for all of this.
a Prodigy P2 brake controller costs under $100 and can be easily installed by you. there may be a plug-n-play harness that will cost about $10.
an Equalizer WDH with built-in sway control can be bought, with free shipping, for less than $450. easily installed by someone with a minimum of handiness.
a 3rd party extended warranty is usually a waste of money. PLEASE read the fine print to find out what they WON'T cover. and how much are they charging for it?
