As many know the AC condensate hose drips onto the frame. I've seen many versions of this mod but thought I'd share my experience in completing this mod.
I used a 5/8" ID clear reinforced tubing, it's what I had. Videos I watched said to watch you do not crush the stock tube when tightening. This gave me an idea. I've used brass sleeve bushings on plastic pipe being used on compression fittings. I bought a 7/16" sleeve at a local hardware store for $1.89

I used this inside the end of the stock drip tube to keep the tube from collapsing when I tightened the hose clamp around the extension hose. It was a snug fit but that's what you want.

Once the sleeve was in the tube, I had to heat the extension tube to flare the end a bit so it would fit easier over the stock tube. I used a propane torch and and a pair of long nose pliers to stretch the 5/8" ID tube slightly. Once this was done, the new tube fit over the stock tube. The hose clamp was placed so that it was over the area of the brass sleeve and tightened.

The hose was routed through the brake hard line loop. I fastened it to the hard line with a zip tie. I used a heat gun to soften the tube so I could form it to the shape I wanted. I ran it on the outside of the frame as shown. I installed a hose / cable clamp with rubber insert to hold the end of the new drip hose.

 

I understand that but the fact that it drips directly onto the frame should be something that is looked at

 

My 5th gen 4Runner has been dripping onto the frame since 2012.
My only observation to date is that portion of the passenger side frame stays a little cleaner than the driver's..

YMMV

Edit: And for what it's worth, this being the 3rd gen Tacoma forum and all... My 2018 Sport has been dripping onto the frame for six years now with absolutely no ill effects.
