Sand Mode and Winches

[zipzag]

First, congratulations to Rivian for implementing sand mode. I encountered a new Subaru this last weekend that couldn't spin its wheels even with traction control disabled. Insanity.

Second, what are you considering for a winch? Anyone kinow the max amp draw from the two little batteries?

There have been mentions of a winch option, but it’s never shown up in the configurator.

If I were to do this myself, I think a Warn Zeon Platinum will be required. It looks like the winch will be hidden behind the bumper, thus requiring a remote clutch, which the zeon Platinum has.

99.99% probability this will be the winch rivian offers.

i‘d just dispense with any hassle and buy it through them.

The winch will need to be 12K pound capacity, but I doubt they offer a remote. If its 12V it may also need a higher ampacity 12V charger on the vehicle. I'm guessing that activating the winch will also turn on the 12V battery charger.

The Warn Zero is suitable as a tow truck winch. I don't see that quality being needed for a 0-10 times per year winch.

I prefer a receiver winch mountable front and back. But that doesn't seem practical. I would rather leave the winch at home 11 months of the year.

The warn zeon series is the only one with remote freespool. It comes with a remote, in 12k capacity.

the rivian app has winch controls in it.

My guide told me last week that the winch will be an available option “in the future” and that currently shipping trucks can be “retrofitted” with it. This was in response to a question asking if the truck was winch ready and more specifically asking about how to wire it up since I have similar concerns about the 12v being sufficient to support a winch. She gave me info, but didn’t really answer my question.

I will be headed to the Outer Banks in a couple weeks, of course I would like to take my R1T out in the Cape Hatteras National Seashore (with a permit of course!).

My question is for current sand use, is there any considerations for an EV on sand that vary from normal sand driving tips? My biggest question comes in regard to tire psi...is that still a best practice, with an EV is it as safe to lower the psi due to the significant torque difference going to the wheel?

Just make sure to avoid drum sand lest you accidentally summon a maker.

Without bead lockers the rule of thumb is to stay above 10 psi. But I wouldn't go to the low double digits without a full size spare.

Remember you will be one of the heaviest vehicles out on the sand

IIRC, when running the Rebelle, Emme and Rebecca found 28 psi was about as low as they should go given the weight of the truck.

Thanks for that, I didn't even think of going back thru any of the Rebelle material...I will start digging!

There was definite concern about the vehicle weight when lowering PSI.

Update: Looks like she was dropping them down to 22psi for the loose sand...

I swear I saw Rivian said it was somewhere in the 30s as well. Maybe 30 psi?

Hopefully you weren't going to stay in one of the two houses that fell into the ocean today in Rodanthe!

I never really air down on the OBX beaches...drive smart and usually I'm fine - this because getting air is challenging. Now that you have your own fill system, you'll be king of the red neck Riviera. If you see a LG/FE R1T out there...it may be me.

Saw the houses! That's crazy. It also looks like NC12 requires 4WFD access now too

Thanks for the expertise on OBX sand! Hoping to get to check out the seashore area while there, never been on the sand there.

Hey do you happen to know what's up with the RAN chargers at Nags Head Wood Preserve? Looks like installed in August, still not in service.
