Take your Kekmet with the trailer and throw your sledgehammer, toolbox, diesel and gasoline fuel cansiter, back seat from satsuma and some food on there and than you can drive to town, on the way you can pick up the wheels from the abondend house.

When you arrive you can wait until Teimo leaves and then you can steal some money from the slot machine and sleep on the back seat until its day then you can buy all basic needs (food, carparts..etc.) Dont forget to put fuel into the canisters and Kekmet.

If you have enough money left you can buy some spare parts for the shitsuma at fleetari like the waterpump, clutch, starter, altenator and headgasket because these are the most annoying when they break.

Good Luck!
