Uncle Nelson is a rat faced scumbag. He's on a secret deal with the police for immunity on all drug related crimes in exchange for you and all the suppliers/dealers in Hyland Point. Ever wonder why your RV is blown up by some gang you never see again? It's all planned by Nelson. He can't have you getting away again.

Nelson and his accomplice Albert Hoover are out to get you.

But we won't let that happen. We'll ghost Nelson like teenage girls and keep our sacred RV, while staying away from the cops (well, we edge them later, but that's not the point)

Schedule 1 without Uncle Nelson or Albert Hoover (weed supplier, unlocked by Nelsons questline) sounds impossible. But a couple silly tricks make it not only possible but quite easy.

The first thing you want to do is water the plants in your RV. These two half grown weed plants (which are there regardless of whether you skip the intro) are the key to this method working. Take good care of them, you'll need them and you won't be able to get more product for awhile.

Afterwards, go pick up the cash stashes Nelson left. As long as you never reach the quest to pick up the cash stashes, the RV won't blow up if you take them. In case you've forgotten, they're behind the fountain, behind the supermarket, and in the central canal (images below). Note that this isn't strictly necessary. You can proceed with the money you have.
Supermarket
Fountain
Canal

Alternative ways of getting cash at this point are:
1. Get the baseball bat from the basketball court and smash every cuke machine and ATM in the city. This will net you a decent amount of cash.
2. Pickpocket citizens (ideally from uptown or suburbia, as they are the richest)
3. Selling a FEW baggies of the weed you've grown. Remember, you have a very limited amount. Don't go overboard. Save at least 6.

In order to start making meth (your first consistent way of making money), we need to reach Hoodlum 1. This requires about 1000 xp. There's several ways of getting XP, but unfortunately most of them involve selling drugs, which we can't consistently do. The only other way is evading police. Now, if you want to simply punch cops and run away a few dozen times, have at it. However, there's a way to do this while sitting AFK. Here's how:

First of all, wait until before curfew. Then, you'll want to go in front of Taco Ticklers. You need to get on top of the telephone pole in the screenshot below:
Pole

To get up here, you need significant verticality. The most effective way is to hit your spacebar twice in very quick succession, netting you a significant jump boost. Use two fingers for this. You'll want to jump on the piss hut, then on top of the warehouse, and finally to the pole.

Another method is to instead hold a box (those found around the map that you can pick up, stand on, and throw around) and jump into it while holding it at a steep downwards angle. If you never touch it, the angle is too shallow. If you jump over it or it touches you and drops, the angle is too steep. This may take a few tries. Eventually, you'll rapidly fly upwards.

The third method is to wedge yourself underneath a roof (such as inside the Taco Ticklers doorway). Then, spam jump. You'll fly upwards when you exit the doorway, and if you can control it you'll want to land on top of the pole. Alternatively, land on the freeway and then jump onto the pole.

Once you've gotten up here, wait for curfew. You'll notice that the cops in front of Taco Ticklers will notice you. If they don't shift around on the pole until they do. Once they detect you, they'll run up to the pole trying to arrest you. Unfortunately for them, you're too high up, and they end up not being able to see you once they get close enough. You'll 'escape' them, and they will walk back to their posts. You've netted 20 xp doing this. And you can sit here AFK, the cops running back and forth. After 50 goes, give or take, you'll have enough XP to unlock Westville, and thus Shirley the pseudo dealer.

If you haven't noticed by now, you're kinda broke. As you have also noticed, there's solutions for everything. But don't worry, cash is a short ways away. It is at this point that 98% of Schedule 1 players quit, as it's time to hit the casino!

This part of the guide is very simple. Go to the casino, and play slots. Start on a low bet, and make sure to run all the machines for maximum profit. Once you get a jackpot or two, you can up your bet safely. Rinse and repeat for a good while and you'll have tens of thousands of dollars — enough to afford a basic meth lab and ingredients.

Now, you'll need to get in the warehouse. If you're keen, you'll ask why I only got you up to Hoodlum 1 instead of 5, since you need to be Hoodlum 5 to enter the warehouse. And this is because it's very easy to clip inside the warehouse. Be aware that this is considered a "glitch" strategy, and thus if you want to be a good boy for TVGS you'll instead wait an extra hour on the cops to get enough XP to get in there organically.

As always, there's three methods.

1. Clip in with the garbage bin. In-between the back of the pawn shop and the warehouse is a garbage bin. Pick it up and drop it a foot or so in front of the silver garage door. You should be able to stand on top of the garbage bin against the door, but with air below your feet. Then, equip your skateboard. If done right, you'll practically teleport inside the warehouse. If you can't get this right, try #2.
2. Punch an NPC, particularly one that chases you, and lure him to the door. He'll get near the door and open it, at which point you can slip through. If you're a pacifist, try method 3.
3. Walk backwards into the door. Equip your skateboard, and the exact frame you get on the skateboard press the interact key to open the door. This is incredibly difficult, but also opens the door for free.

Now that you're in, buy a chemistry station and a lab oven. Buy a sufficient amount of Acid and Phosphorus (sufficient = as much as you can carry). Keep it somewhere safe.

Technically, you can make meth in the RV, without buying any properties. You also can't get the $800 room or the $75 motel room without doing Nelsons questline. Or can you? It turns out, these are already unlocked. You just have to clip into them using the methods from the last chapter. You can't open the door, but the floor is yours and you can use it how you wish.

Alternatively, you can put thousands in your bank you earned from the casino and use it to buy the bungalow. Or use the RV. Your choice.

That weed you got at the very start of the game finally comes in useful here. Pick it up (in packaged form) and head to the western gas mart, where Meg Cooley waits for you. Give her samples until she becomes a customer, then sell her product until you befriend her enough to unlock Shirley Watts.

Hit up Shirley for a dead drop of pseudo, and go to wherever you have placed your meth setup and finally get to cooking. Make meth, package it, sell it, and you've finally reentered the main gameplay loop of Schedule 1. Proceed with the game as normal, enjoying your luxury mobile home. while Nelson rots in prison. Remember, you're the good guy.
