For most of my life, I always fixed my home, cars, appliances, televisions, rv's, and assorted toys myself. Partially because it saved a couple coins, but mostly because I tended to get better quality that way. Now I'm more inclined to pay someone to put in a new fence, or work on the car. Most of the house interior related stuff I still prefer to do myself. I do all my RV work if it isn't warranty, mostly because you really need to upgrade and beef up everything which the shops don't tend to do. We roam all over very desolate parts of the country in our ATV, so I do all the maintenance and upgrades on it myself. I don't trust the shops to do a quality job and most importantly to really look over and fix anything that needs fixing or modifying.
The stuff that's important to me I'll probably keep doing myself until I'm no longer capable.
