I just paid $160 for my tandem trailer wheels. He found one bad bearing and had to replace it. He repacked the others and adjusted the brakes.
I found this dealer/RV park owner a few years ago when I needed my awning replaced.
He charged me $600 for a new awning and the installation, and the awning now rolls up and comes down much better then the old one did.
I'll continue to go back to him even though he is over an hour away.
The big box guys will make an appointment for several weeks or longer from when you call them, and this guy will take you within a week.
If any one is around the Asheville, NC area, I highly recommend him.
It is Wilson's RV park
