I know this discussion has been brought up before, but I just had to bring it up again. I'm currently thinking about getting a 2010-2013 Chevy Duramax long bed 4x4. I'm just kind of worried about it being too heavy for PINS, Not to mention I go back to Yarbrough quite often. I want to know if any of y'all take y'all's diesel trucks back there through Yarbrough pass and I know you can get into some loose sand going back there at times. I know the surf side has some loose sand at times too. I just want to get input from the diesel drivers. I currently have a 2012 Chevy 1500 4x4 lifted with 35's, and It does great, just been thinking about getting a diesel. Thanks in advance!

It's been years since I've been back at Y-pass in a diesel....

But back on topic.... All I'm saying is that I've passed 4x4 diesels straight buried to the cab in my tacoma in 2WD.... That's all I'm saying....

I've been down there with my 3/4 ton diesel a few times it's all about tire displacement the wider the bigger the foot print. I go to the jetty a few times a year never had an issue

Just pushed my 3/4 ton Dodge Diesel 4x4 to the 28 with no real problem. The Ainsworth guys were driving F350s. I did lowered all four tires to 40 psi. So it can be done. With that said I think the guys with lighter trucks had an easier time than big heavy trucks.

I've got a 06 ccsb duramax. I had 33x12.5 Bfg at and I have overheated both the tranny and motor on it. I was loaded really heavy and was pushing hard in some rough conditions. I've got a full replacement in front and rear, with steps nerf bars, and a headache rack. I'm sure that don't help it but that is my experience. I now have a 285 nitto trail grappler and they do great in the sand. I believe it is cause of all the lugs on the sidewall. It can be done but now I just cruise and stop every 15-20 miles and let it cool down at idle while I drink a beer. My old 98 z71 on 33 Bfg at's would run circles around my dmax. That I believe is the best beach truck there is.

I wouldn't do it without some good sized tires. My 1/2 ton gasser does quite well with stock tires.

I have used a Dodge Diesel long bed, Ford Diesel short bed, and two chevy (gas) long beds in the sand over the years.

Hands down, the Dodge out performed the others by far. I never even had to use 4L anytime; even when pulling people out.

Ford, I never had a problem or even a close call, but I did have to use, or at least felt I needed to, 4L

I have never been stuck with my chevys, but I have had to work them hard and had a few occasions that I was concerned. Mind you, they were both gasoline.

Regardless, know your truck and know your terrain.

Most of all, know your limitations and don't push it too far.

2001 F350 - Sometimes had to get into 4L just to get started out of the soft sand.

Good luck!

I used to have a ford f-250 double cab diesel and took it back to Yarborough all the time fully loaded. I got it stuck going back in there a few times too-mostly driver error.

If you want to drive a truck like that back there, be prepared. Soft dry sand is not the worst thing in the world and with a little know how you can extricate yourself pretty easily or avoid getting stuck altogether. In addition to the usual tow ropes, shackles, sky jack and shovels-

I recommend you carry 4-1' X 6' strips of 3/4" plywood. These can really get you going and can save a lot of time if the sand is really deep or if it wants to keep falling in from the side dunes. Also they are very handy around the camp for wind blocking, little tables, cleaning board etc.

Get a high quality 12V air compressor-not the one from Harbor Freight. I recommend the Puma brand-it has a small tank and can fill those big tires in about 3 minutes.

Let the air out-for a big tire that is running 70-80 psi, going down to 40 will help some and give your transmission a bit of a break. To really get a bigger footprint, you can take those suckers down to 15, where you will increase the size of you footprint by ~250% The Baja guys do it all the time where they take a 50psi tire down to 6-8 psi. If 15 makes you uncomfortable try 20-25 and be on the lookout for a side puncture issue-not really a problem going through the pass as long as you walk it first and clear out the debris.

Unless the sand is packed heading down, i will always let some air out just to help with the ride and give my transmission a break.

I have never been stuck leaving the pass-always on the entry. Try to pick as straight a path as possible and get a good head of steam in 4 low going in there. When I have gotten stuck it has been because I got cute at the end slope and did not maintain speed.

Check out the serious sand driving forums-there is a wealth of information in those things-often times it is a matter of how you drive rather than the vehicle you are in.

All that being said I have switched to a Tacoma. The big trucks do have their advantages in that you can carry more without taxing your suspension or modifying your truck. More interior room for sleeping if you do that and you can be a real good Samaritan on the beach with almost any vehicle needing assistance.

Good luck.
