    Looking for info on prepping a 2018 4Runner for potential water crossings. Snorkel brands suggested, diy or professional install, other areas needing attention to avoid problems.
    Hope I got this in correct place this time.

    It seems like most normal folks only need to extend their differential breeders and transmission breather. That is phase 1. If you really think you will have water all the way up to your air filter intake, then you definitely need a snorkel.

    I think ARB has a differential breather extension kit. If you wanted something professional looking you could do that, or you could just buy rubber hose from your local auto parts store and do it yourself.

    There are other things to consider when crossing water, like wheel bearings and engine pulley bearings. Premature failure can definitely result with frequent extended water crossings.

    Make sure you do a test cross him first on foot, especially if you don’t know what kind of bottom it has. All the professionals I see always send someone ahead with their pants rolled up to check the bottom for softness or mud. I know it stinks doing this, but it also stinks being stuck in the river for six hours. Don’t ask me how I know.

    Very helpful. I don’t plan to do it often if at all. But would rather be ready in case.

    Be prepared to cut into that new fender...

    I’ve never ran a snorkel, and have been into water near the top of my 31” tire. Snorkel would be needed for water that goes over the hood... just something to keep in mind.

    Might wanna consider your limit and the limit of those people in the car with you before biting off on that one :)

    Not looking forward to cutting the fender. For sure. And I actually have zero desire to go in deep water with it. But I have to plan for worst case scenario. I’m planning some off-grid shooting/survival schools and want to cover my bases. It would suck to have your instructor cancel your class cause he got water in his engine. LOL.

    I am sure you are aware, but if water is high enough to get into your engine it is also filling your cab. Ask me how I know..

    And Arkansas mud smells like ass.

    It’s actually more a shooting/hunter prep school. We will go to various locations. Get some animal vital targets set up and practice real life hunting scenarios. I teach shooting out to a mile here in Texas but we are planning these in more mountainous areas. Additionally I have other instructors that can teach skills for when things don’t go as planned. Medical, land nav, vehicle recovery, etc.

    Sounds cool!

    I'm a certified NRA Instructor and shoot some competitively, but am looking to get out more hunting (only been a few times so far). Skills when things "don't go as planned" are very practical and necessary when you are hours away from any assistance.

    You need to determine how high the air box is off the ground, in my case it's about 42" before I have to worry about water reaching the air filter. My truck has the drive train vents high, about 40" or so above the surface. If you have really good door rubber it should seal out a few inches of water. I think I would limit any water crossing to 24-28".

    I do some long range with a 6.5 Grendal and Creedmoor, remember not to shoot across a roadway or waterway.

    Luckily we can find something in Texas to hunt pretty much year round.
    That sucks. Really try to avoid that.
