Off the grid, and off the plastic.. A true goal. Plastic is used here, all the time to get things accomplished, and parts bought for various needs and vehicles. Otherwise it is a hard look at most purchases. I yard sale a lot, dumpster dive alot, and build a lot. Being close to major cities I sell evrything from dog houses, to yard barns and chicken coopy things, from found and converted discards. I am selling gas masks, and motorcycle helmets, power tools and truck racks on Craig and the Bay. I make a bit off each thing, but it all adds up. No matter what road you take, stick to it, and make some milage count.
Be carefull on the insurance thing, dropping insurance is reason to call in the note, and that gets into court and lawyer money, with a blip on a credit report. I dont do well with payments, and usually pay of vehicle notes early with tax returns and windfalls. That is just me. Some states allow for a property bond, for public liability, but some people dont take that risk. Bottom line is you are never safe, but manage your money safely, it is controlled risk..
I am cheep, but give new meaning to the word of Frugal.
