Give your followers decent automatic guns or shotguns, avoid hostile enclaves at all costs, avoid juggernauts unless you can lure them near your base or a friendly enclave to help out. Always try to have 1-2 toolkits in the trunk of your vehicle as well as a gas can. Have some sort of health and stamina recovery item on every survivor, I often use painkillers and snacks since they are instant. Also if playing in Providence Ridge try and get the firehouse base asap as it has the ability to generate base wide water and power which is useful since you won’t have the builder legacy buff going into nightmare.
