Hi and thanks Bruce
Twisting was not something I had considered.
To test for twist would it be a matter of doing some measurements bewteen sidewalls front and back and perhaps corner to corner.
I have new bolts / washers for the tapped area and it will determine whether a new tap will be required there. I'll eliminate that this arvo.
I had advice that I should have some "tension" on the pivot bolt and I certainly couldnt move the bottom bed at all by hand. Should the "tune" movement be relatively easy. I guess the more tension on everything the more likely the tapped area could be stressed. Once the lower pivot bolt is tightened I cant inmagine it would be easy to shift. Its a very large bolt and nut.
Thanks Guys
Rob
