Almost all of the wheeling I've done has been by myself. I carry a spare part for everything, extra sensors, filters, fluids, alternators, starters, brake lines and all breakable parts I can think of. I also carry a complete toolbox, right down to small punches, chisels, drillbits ects.
When I'm alone, I still beat on my shit, but to a lesser degree than when with some of the guys on here. It is critical to know how to fix your stuff.
Must have a winch, come-along, shovel, wooden plank, chain and snatch block.
Pack extra clothes, food, sleeping back, pistol/rifle, smoke, lighters and extra beer.
That is what I bring, everytime I go out alone.
That being said, I was almost an eagle scout, I was an ground pounder in the Army for a few years, and grew up in the country. I have been an outdoorsman my entire life. Could something happen while I wheel alone, sure. But it wont be because I wasnt prepared. Is wheeling alone for everyone, no...Is it for me, yes, it is preferred over big groups. What I dont appriciate is people flaming people like me for wheeling alone, when they dont know the personal circumstance behind it. In most cases, I think wheeling in a big group of dumbasses is more dangerous than wheeling alone.
