Receiver maintenance, you may want to check.
After a few years of road salt and wetness in the midwest, I decided to sand and scrape some of the rust that was developing on my receiver.
To my shock and I suppose good fortune, I checked the bolts that hold the receiver together. I have a Dalan. About three of the nut/bolts attaching the the cross bar to the the side brackets were quite loose. I tightened them up right away.
It goes without saying that I will be checking connections on our receiver a few times during the season, along with the bolts that loosen on our Equilizer after each trip with the AS.
I think it was a good idea to to clean, re-prime, and top-coat the receiver, to slow the process of corrosion.
Just some advice.
Sometimes I wish I were living in the stone age. Then I would know I'm the smartest person in the world.
