$615 installation works out at about 4-5 hrs of dealer time.
If LR trained technicians can do it in that time (shut up DB :p), then surely you can do it over a day or so.
I would imagine the front bar/grille comes off then the 'bar' is mounted up & the whole lot refitted.
Put on a BBQ lunch & you might even get a few of us around to give you a hand :).
