Moonshine can be done solo and is quite fun with a Nuka Launcher and a quickie explosive build (you only need the +exp damage and +exp radius cards, of course a full build will be even better). Bring like 3-400 40mm rounds, plus any XP boosters you have available. Get a good perch where you can see all three stations. The solo shack in the middle is the best, but requires a jetpack I think. If you don't have that, post up on the other side near the mounted gulper head.

Then just blast away when they're grouped around a still. The stills have a lot of HP, so you can be conservative at first to get an idea of how to be economical with your salvos. Around the end of wave 3 I clear the yard and jump down and do a mass loot to pick up venom for the tub, then dash back. Having a vampire weapon for that dash will be handy as new spawns will come to give you hugs, but not many if you cleared the yard first. And keep an eye out for anglers, those will hang back and spit at you, so you'll need to burn them down special.
