Bummer on the garage, but congrats on getting rid of the ole bling guard. The TJM is very straight forward and easy to install. You should be able to do it yourself, but it helps to have someone help lift it. I have done one on and off by myself by laying on my back and lifting the bar with my feet and lining up the bolts. The biggest thing is just pulling your old stuff off. Save the wheel well plastic pieces and fasteners. If you are planning on putting a winch on there, then make sure to put the winch tray in first. If you do it later you will have to remove the bumper, still not hard. Good luck and if you get in a jam just post and someone here will surely be able to help.
Cheers,
Mike
