Your own garage... buy an air compressor, a 33 gallon craftsman at a minimum, buy an impact gun, craftsman’s $99 composite is a great starter, and some 3/8” air hose (or a reelcraft or coxreel air hose reel if you wanna go all out)... make sure you pick up a comprehensive set of hand tools too...
Buy some repair manuals, and watch how to do stuff on youtube.
You are now more knowledgeable than most people driving cars these days, and your knowledge will help you on the trail...
Only visit a shop in case of an emergency, or when a lift is absolutely neccessary...
