    I'm looking for a new truck and think I just ruled out the trail boss after skipping around a 200 page post on the leaks. I guess it is still happening on the 2021's. Kinda sucks I just found a base 6.2 I could probably pick up for a little under 40k.

    In that thread someone mentioned there the tundras did it too. So I searched around and only found 1 complaint with the 3rd gen. Looks like it was just a 3rd brake light seal. Most of the complaints I found were 1st gen.

    I didn't realize all the crew max windows come down which I like. But wondering if there is any issue with leaks either with the window or brake light.

    There was on guy that had water in his cab and mentioned the 3rd brake light. I thought his was missing the seal though...can't remember.

    Yeah, haven't heard of any issues here. The Tundra is definitely less likely to leak than any of the domestics.

    But if you're set on a Trail Boss, you could buy one with a fixed rear window. That's what I was considering until I read about all the other issues they're having. :rolleyes:

    Switched over to a Chevy LT TrailBitch from a Tacoma back in 2019. Got rid of the POS 2 months ago and went with a Toyota Tundra. Long story short I bought the TrailBitch and had nothing , but issues. Back up camera at night was horrendous. The touch screen would black out completely and I had no access to it. Check engine light every other month because of a terrible ECM. And if that wasn’t enough the 8 speed transmission was a complete joke. Sometimes when going into reverse then drive it would hesitate upon gas throttle other times it would jerk you forward. Right before I traded it in it started making a loud screeching sound when putting it reverse. I owned the truck just over a year and couldn’t wait to get back into a Toyota.

    Thanks all for the replies, I found no other leaks with the tundra in more searching. I'm really sensitive to mold/mildew so that's the last thing I need in a new truck. It looks like it's not just the window opening leaking but the bigger issue may be that big spoiler/brake light on top. Something with sealing the mounting holes and even after being repaired still happening. Probably for the best saved me from a bunch of other issues with GMs from what it sounds like.

    My 2020 tundra...no seal or gasket in the third brake light lens (high mount brake light with cargo lights). Either Toyota forgot to put a gasket for my truck or they redesigned the lens without the need for a gasket. Someone with a 2020 and up model should check if they have a gasket in their lens.
