Thank you everyone for your comments..
I used wood for the cradle as it was all I had lol I'm sure a sturdy aluminum, or steel one could be fabricated, but this looks nothing like my original design.. it kinda evolved as I went. It works, so it's good :)
It is not attached, at any point to the frame. It sits on it's own base so it's weight holds it. It also has nowhere to go. And I kinda pack it in there once the slide is in there is no danger of it migrating...
Sue T, I love that rack.. My bike is nearly twice as heavy as yours though.. Believe me, that would be a fantastic solutions for me, but I don't trust my frame to handle the stress. I guess a phone call to the makers might be a good Idea, but for now, I'm happy with what I have. :)
So, my maiden 5th wheel trip was largely a great success.. On arrival to the site, I had 3 "truckers" offer to park it for me HAHAHA.. Was it really that obvious?? No sir, you do not drive my truck!! I managed fine, and had a great time. Lots of friendly advice and lots of friendly people.. HOOKED!! WOO HOO!!!
So the trial run was a complete success! :)
Next year is out 15th anniversary... So, FLORIDA, and Disney World.. Oh Yeah!
Can't wait :)
