A bit higher than I'd expect... Well.. depends...
Are you a Good Sam's member? Significant discount from CW on the labor if you are. In Oct 2014 I paid $2800... included:
- Roadmaster Invisibrake
- Falcon All Terrain Tow Bar
- Base Plates ($459 for my Wrangler)
- Brake Light Relay
- Safety Cables
- Installation of all of the above.
Without Good Sam's would have added $430 in labor (a membership is far cheaper...)
$320 additional was quoted for 2 year protection plan
With those additions $3550... And I had already done the Jeep OEM wiring harness in the Wrangler.
So you aren't that far off.
At the time - the equivalent from Blue Ox was quoted by a different dealer over $1000 more.
