Thoughts on Champion Generator (not Yamaha or Honda)

I inherited a Champion 4000 and it has served me well. It is loud so If I need prolonged power in a public area I switch to my Honda.

Pros.
1. For 5 years it has lived in the back of my truck in the elements without complaint.
2. Starts first pull every time
3. Runs on bad or old gas that my Honda won't.
4, I do not worry about someone stealing it
5. Around $350

Cons.
1. Loud
2. I don't have to worry about someone stealing it.
3. Some screws vibrate loose. Needs occasional maintenance.
