Important Precautions for Your Off-Road ‘Skoolie’ Build

Ever wondered what happens to retired school buses? Ever wanted to build your own overlander? Ever heard of a Skoolie?

Skoolie = retired school bus transformed into an overlanding vehicle.

When you transfer a bus from a suburban path to a remote washboard road, you’re multiplying the mechanical stress. And that, unlike the purpose-built overland rig, a school bus conversion (aka Skoolie) is heavy and carries a large center of gravity that can cause catastrophic failure without careful planning.

Be it piloting a ‘Shorty’ (or a full-sized International), these safety checks are imperative to all aspects of the off-road bus life.

Confirm Your Actual GVWR

When you’re part of the Automotive Outdoor (offroading, overlanding, trailing, etc.) community, you need to start by not exceeding the Gross Vehicle Weight Rating (GVWR) of the vehicle. This is one of the most common errors in the Automotive Outdoor conversion community.

With heavy wood framing, full water tanks, and recovery gear, it’s quite simple to ram a bus past the engineering edge. Heavy load causes the braking to be less efficient and the stopping distance to be longer, and can be a recipe for disaster in steep mountain grades.

Your fully loaded build should always be taken to a CAT scale before heading into the trail to make sure you aren’t a rolling hazard.

Check the Bus Bar and Electrical Vibration Resistance

In the overland world, a bus bar generally means the electric distribution points in your power system.

Vibration from the road is the enemy of electrical connections. Check that your negative bus bars and fuse blocks are rated for high-vibration environments and that all wire is properly loomed out and secured.

The ‘City-to-Trail’ Transition

Often, the most dangerous part of a Skoolie overland journey isn’t the trail itself, but rather the back streets you pass in the high-traffic corridor on your way there.

City buses are longer, they’re (much) heavier, and they’re also far less agile than you.

They require higher angles when turning, and they have a much longer stopping distance. And they have larger blind spots compared to you. And since they go to all the curbside stops and then merge back into traffic all the time, you’ve got to respect them to avoid an accident.

Because if you end up in one, your large rig can do only THAT much. Plus, even if everything’s fine, you still have to deal with the law.

Here’s a quick example of that:

If you’re in a traffic accident with a bus (or vice-versa) in Chicago, which operates under Illinois Law, you’ll have to deal with a comparative negligence system, which means that you’re allowed compensation ONLY if you’re less than 50% at fault (even then, your compensation can be lowered based on your fault percentage). If that happens, you’ll definitely need a Chicago bus accident lawyer to deal with all that.

In comparison, if the collision happens in NYC (New York Law), you’ll deal with pure comparative negligence, where you can get compensated even if you’re 99% at fault (but the compensation is proportionally lowered).

It’s still good to have a lawyer to maximize compensation, but you’ll get ‘something’ either way.

And keep in mind that you’re driving the bigger vehicle, meaning there are extra eyes on you.

Suspension and Tire Age

Bus tires do not ‘wear’ their tread in a transformation situation, and they will simply ‘age out.’

Look at the DOT date codes on your sidewalls. Even if your tread looks deep, rubber that is over six or even seven years old can dry rot to the point of a blowout in the heat and strain of highway speeds or air-down trail driving.

Also, look at the spring hangers on the leaves for cracks, as the strain around off-camber trails can shred the old hardware.

Conclusion

If you take care of your skoolie, your skoolie will take care of you.

So just make sure the transformation has been done correctly, up to standard, and that all the mechanics are solid (brakes, steering, suspension, your tires, and your engine).

Enjoy the trials!
