Climbing Sand Hills

This past weekend my dad and I headed to Knolls Utah to try out the Raptor in some Sand. We had a great time and both trucks performed well. We essentially have the same truck. No tune, no aftermarket suspension, I have a CAI and more aggressive tires but that's it. I have searched the term "sand climbing and didn't find an answer to my question. While trying to climb some steep sand hills both trucks would cut power when they started to dig or lose traction towards the top of the hill. We both had the trucks in Off-road mode, 4X4 High and traction control off. As you can see in the video it was hills similar to that. Any ideas on why the trucks do this or is there another mode we could have put them in? The trucks would have made it up the hill if the revs would have kept up. I would appreciate any advice you guys would have.

Did you hold TC down for 10 secs to fully disable it or just tap it? Also lock the rear by pulling out the 4x4 knob. Or try manual and keep it in 2nd (or lock out all gears except for 1st and 2nd)

Is it actually cutting power or shifting into too high of a gear? Did you try 4Low?

Yes held it down so it was completely off. And yes the rear was locked. The back end would hopping around. We would just reverse down the hill.

Trailer sway control turned OFF?

It was cutting power, I didn't try 4 low because it would have slowed the truck down to much and you had to climb fast or you would sink.

Jimbo! You may be on to something, I am betting that was it. It acted like a safety feature was killing power and I think you may be right. I will have to head out to the dunes again and see if that solves it. Thanks for the tip!

Nice pics regardless!

trailer sway only affects side to side movement of the truck. i have been around turns too quickly and had it happen before. you can not fully turn off traction control in the truck. i think only 2010 you can.

Pull the fuse and disable everything.

Were you aired down?

Just watched your video. Humor me and try it in low (off-road mode) next time. You weren't going very fast.

Here's me in four low on what appears to be a larger hill.

Here's four high on another hill.

Also, be careful turning your tires THAT much - that's how I snapped a CV in the sand on the four low video hill (different time, not caught on camera).

It looks like you simply didn't have enough grunt in four high in first gear to get those tires spinning. You need wheel spin in sand. I don't think any nannies kicked in or anything.
