I did my lift/ axle swap by myself and this is a very true statement. I pretty much do everything on my truck by myself. I usually work until 10pm so nobody wants to help me when I can work on it anyway.
I would have to say the hardest thing that I have done by myself is manuvering a complete front axle under my truck in the dirt around the jackstands that were both in the front (had to pull it in from the side).
The worst feeling though is when you do something like what I did. Finished the whole lift/axle swap and wasnt able to drive it because nobody was around to help me bleed the brakes.
Im not sure about yall but I only trust a few people to help me on my truck and I like doing most things by myself when I can.
