If you watch TV, or movies, and you’re over the age of 40, you know the place. Maybe not implicitly. But you’ve seen it. It’s where Tony Stark was captured by Afghan terrorists. It’s where Captain Picard scrambled across an alien world. It’s where Val and Earl discovered and fought Graboids. That’s right. Alabama Hills is everywhere, and nowhere, all at the same time.
We’ve been fans of the west slope of the Sierra Nevada for decades, and Alabama Hills in particular. It’s easy to access, has great camping, climbing and unbelievable views. Or at least it used to have great camping. Unfortunately, it got really popular with the rise of Overlanding and Vanlife over the last 10 years and that popularity has lead to a lot of inexperienced visitors who are sloppy, inconsiderate and criminally complacent with their trash and human waste.
Littering is a crime on federal land. It’s always been that way. Somehow we forgot about that. I guess we need Hooty the Owl and Iron Eyes to come back and remind us of our heritage of stewardship.
Anyway, this post is about how in the spring of 2022, we rented a camper van and left town for 10 days with the goal of seeing new things and going to new places between Reno, Nevada and Death Valley. It was an epic trip that we’ll never forget. And one thing we’ll never forget is how much toilet paper and human poop we found at a campsite, that was hard to find at Alabama Hills.
When we first took Lightning Dragon to Alabama hills back in 2012, camping was unrestricted—aside from standard BLM rules for camping on public land. blm.gov/programs/recreation/camping.
We camped west of Movie road up near all the rocks and boulders that had good rock climbing. But even back then there were other users camping and driving in unimpacted areas, leaving trash and still burning campfires when they left.
In 2018, we went on a trip with both kids to Joshua Tree and camped in the same area, though it was much harder to find an open campsite because of all the other users there. I don’t begrudge others visiting the places I love. They’re there, ostensibly, for the same reason I am, with the same right and entitlement to the shared resources. My familiarity and history doesn’t grant me priority rights or claim to it. But that trip in 2018 was an eye opener as to the greater impact that increased visitation by ignorant and inexperienced visitors was having.
Once we set up camp and started exploring around the rocks and caves and canyons nearby, we soon found toilet paper tucked under rocks, and full plastic bags full of human waste loosely buried in the decomposed granite. The TP is common, and has gotten even more common, but the toilet bags was a new thing. Apparently there products being sold that use a heavy plastic bag to catch and contain human waste for campers, RVers and overlanders and van lifers. Instead of transporting them back to a proper place for disposal, which if the bag doesn’t contain some kind of gelling agent, is only a toilet or pit toilet, they just tie them off and dump them in the desert.
That was 2018, but we had the same experience in 2022.
It isn’t really necessary to say that this is the wrong thing to do. And it isn’t really necessary to go as far as to say that is incredibly irresponsible and inconsiderate to do this. But I guess I just said it. Commiserating with me in the comments, is appreciated, because it helps get this content seen more, but what will actually help?
Awareness. Talk about poop. When you go camping and you share images and posts and thoughts and memories, talk about how you cleanly, comfortably and responsibly contain, and dispose of your waste.
I made a video a while back about how to dig a cat hole. And that had been the standard for human waste disposal for many, many years. Unfortunately traffic in areas like Alabama hills is too high for that to be an acceptable way to deal with poop. We need to pack it out. We cannot leave it there.
DON’T BE A JERK
Now I don’t want to be the guy who tells people what to do.
Or where you should or shouldn’t go.
But whatever you do, and wherever you go, when you get there.
You can not shit on the ground and leave it there. You can not toss your shit bags out on the ground, kick some sand over it and leave it there. You can not treat wild places like your own personal landfill and then go on Instagram and complain about government overreach when it all gets taken away.
This is our fault. We did this. Ourselves. But we can fix it.

BUMP STOP BASICS
1. You definitely need bump stops
2. Bump stops are a piece of rubber that prevents metal-on-metal contact when you hit a REALLY big bump with your car or truck.
3. Your vehicle comes with these from the factory.
4. Unless you’re getting really extreme, or you just like making things complicated, your stock bump stops will work just fine.
If you want to move forward to making things really complicated, here’s what you need to know.
Our Tacoma has Old Man Emu’s BP-51 suspension, including shocks and springs. So it sits about 2.5 inches over the factory ride height.
WHY YOU MIGHT NEED DIFFERENT BUMP STOPS
Many lift kits come with a spacer that moves the bump stop closer to the axle. This is to prevent the shocks from bottoming out because the collapsed length exceeds the clearance of the stock bump stop. This would cause the shock to bottom out, which might be bad, depends on the shock.
The Old Man Emu kit does not require modified bump stops. The instructions do not require or recommend modifying the bump stops. The specifications state that it is compatible with 0 lift and the collapsed length of the shock is only about an inch greater than the stock shock.
So If you like to keep things simple, you can stop here and keep using your stock bump stops.
TIMBREN ACTIVE OFF-ROAD BUMPSTOPS
https://amzn.to/4bBaij9
I installed Timbren Rubber bump stops a few years ago to help with that, and you can check out the video where I talk about that. The short story there is that even though Timbren markets these bump stops as softer than stock, they are not. When the truck hits them it’s jarring and bouncy and I don’t love it.
Sumo Springs
https://amzn.to/3wlbpU4
A few months ago Super Springs came across my video and asked if I wanted to try their Sumo Springs Product. Sumo Springs are a bump stop made from micro-cellular Polyurethane foam. They come in three different densities depending on the weight of your vehicle. Some sump springs can be used for carrying constant load, like an overload spring, but for my purposes, it’s just a bump stop.
TOYOTA LEAF SPRING BUMPER
https://parts.camelbacktoyota.com/oem-parts/toyota-leaf-spring-bumper-left-right-rear-4834104100?c=bD0xOCZuPVNlYXJjaCBSZXN1bHRzJmE9dG95b3RhJm89dGFjb21hJnk9MjAxNyZ0PXRyZC1vZmYtcm9hZCZlPTMtNWwtdjYtZ2Fz
So let’s compare. The stock bump stop is short and made of very hard rubber because it’s meant as a last resort padding in case of big impacts. It’s about 61mm of rubber.
The Timbren bump stop is made of a similar black rubber, but it’s hollow inside and has a bellowed structure to allow it to be softer than solid rubber. It’s much taller at 95mm and is designed to impact earlier in the travel to spread the harsh stop out over a greater distance and time.
The Sumo spring is taller still at 139mm and is made of a completely different material micro-cellular polyurethane designed with less bounce to soften harsh rebounds, the exact thing I was looking for.
DISCUSSION
I’ve been driving around with sumo springs on the driver’s side for about a month and Timbren bump stops on the passenger side. I definitely notice that the bottom out is harsher with the Timbrens. Semi-quantitatively, the sumo springs are 1 cm thinner when fully compressed and compress over a longer distance, so they are noticeably softer and theoretically allow more axle up travel when hitting bumps.
The Sumo Spring really delivers and I’m definitely glad to switch. while it’s a little taller, it interacts over a greater distance, making its effect a lot more subtle. Plus, the material doesn’t rebound as fast and makes for a much better experience.
When it comes right down to it, neither the Timbren Active Off-Road Bump Stops nor the Sumo Springs are actually bump stops; they’re overload springs. They are there to augment the leaf springs when you put a load in the truck so that you don’t get excessive sag.
If you need the extra load-carrying capacity, then that may be a tradeoff you’re willing to make. How to Choose The Right Bump Stop for Overlanding: Timbren vs. Sumo Springs vs. Toyota](https://i.ytimg.com/vi/a-pyOaKsY3c/mqdefault.jpg)
