Took my GC into Camping World to have them install my trailer brake controller. This after I took a close look at the project and got cold feet. If I'd had any previous experience working through the dash I would have done it, but as it was I couldn't find anyone here, at Tekonsha or NAPA who could advise me EXACTLY how to do it, so I took it to the "experts".
Turns out Camping World knew less about my rig than I did, and doubled their price once they got started. And while they certainly have a lot of experience installing brake controllers, they still managed to install mine crooked, and used the wrong screws attaching the controller to the bracket, stripping it.
On the up side, the controller is mounted to the glove box as I wanted and is out of the way of my knee, and is readily accessible.
Hopefully I'll get a little more Sack when it comes to future projects, as it was only fear of the unknown that kept me from giving it a try.
