Hey guys, quick question. I have a 1997 4Runner 2.7 with 5spd/4x4. I'm thinking about putting an ARB up front, and was just curious if the extra weight/shape of the bumper would impact my MPG/driving dynamic at all. It's a great little vehicle, and I love that it gets 22mpg on the road, so I want to keep that up. Also, how hard is it to mount one?
