Overlanding & Vehicle Setup

10 AWG for a run up to about 20 feet, 8 AWG beyond that, 12 AWG only when the run is short. The compressor maker’s own wire table, the voltage each gauge loses by length, and why thin wire shuts a fridge off with a healthy battery.

The honest minimum recovery kit for a stock-ish 4×4 travelling with a second vehicle: one kinetic rope sized from the door sticker, two soft shackles rated above it, a rated shackle mount in the receiver, boards, a shovel, a plug kit and a compressor. The sizing math, the picks, the two items named in the fatality reports, and why the winch can wait a season.

A second battery that runs the fridge for days and never strands the truck comes down to five numbers: what the fridge really draws, how big the bank needs to be, how many amps the charger should push, what gauge the cable has to be for the round-trip run, and where the fuses go. The math, the picks, the wiring that makes or breaks it, and when to skip the build entirely.

The honest split: cheap traction boards work fine until things get genuinely bad, and then only the good ones survive. When MAXTRAX is worth it, when a budget pair is plenty, the technique that stops you melting either, and what to skip.

Two specs decide it: CFM (how fast it fills) and duty cycle (can it air up all four big tyres without overheating). The set-and-forget pick, the value workhorse, the bombproof one, what size you need for 35s vs 37s, and the cheap inflators to avoid.
