Self Install vs. dealer/technician install

I thought my Demco base plate on my Toyota Corolla was pretty straight forward. I also installed the kit from Rodemaster to use my car lights with the diodes. That was straightforward also. The only issue I had was cutting away some plastic fascia for the base plate arms to go through. It was a full day's work but after it was done it was nice to just put the car in neutral and go after hooking up. It is nice not having to mess with lights each time you hook and unhook. Same tow bar and setup since 2004, used Lock tight on all the bolts, never loosened. The only other suggestion is getting the steel tow bar, it has a higher tow rating than the aluminum bar and is cheaper.
