The Trailer Saver looks interesting. I was concerned about pulling it out but after reading I can just pull the pins and lift it up with the trailer and leave it there.
I will check the goose box to see if it already has the air dampening. The guy we are buying it from is going to deliver it as I have no way to move it. Thanks for the tip on the air style pin box. I am sure with a 40' trailer the pin weight is up there. I read it at around 2,600 but I am sure that was a dry weight and not actual.
Thanks for the information. Better to learn from others than by trial and error. I'm good at error.
