I've gone hunting with my 4Runner and Tacoma and hit deer with both causing considerable damage to the front of my vehicles. I decided I was going to install a grill guard on my 2018 Tundra to at least lessen the odds of damage. I could not find a guard which was supposed to work with the radar (I asked a number of companies, including Ranch Hand) and they all claimed the radar would not work after the install. I decided to get a guard I could modify (cut a hole in) to get it to work so it had to have no tubes, etc., in front of the badge. The Ranch Hand seemed the best bet - if nothing else you get to keep the tow hooks.Because I'd never installed a grill guard before and because the Ranch Hand instructions are "sparse" (and incomplete) I thought I would do this post to show you how.Unfortunately I can't figure out how to post images so here is a link to the instructions on imjur.com: https://imgur.com/gallery/0oY5P1U I figured I would install the guard then cut out for the radar. When I started the truck I noticed I had no warning about the radar and the parking sensors worked fine. I turned on the cruise control and again, had no error. So I took the Tundra for a test drive and was delighted to discover radar cruise control worked perfectly.So, the grill guard works with all sensors unmodified, which was a nice bonus.The one thing I still have to do is to plasti-dip the guard carriage bolts as they will rust pretty quickly and I'd rather they be black like the guard.
