Tow Bar base plates for Lexus GX470
I am looking at setting up my wifes Lexus GX4780 as our flat tow vechicle. I'm planning to do it myself and wanting to know if anyone in the community has a recommendation on which vendor to purchase. In addition, how hard is it, any special tools required, do the base plates mount directly to the frames pre-drilled holes, etc.?
Thanks in advance
