ETsC10, I try to move the truck out from under anything I pick up but the problem was that I have limited space and the cherry picker legs where under the chassis in such a way that the tires/wheels on the frame would have to drive over the legs of the hoist. Even if I am able to roll the frame out of the way, I still have to move the cherry picker to the place I want to drop or set the enigne or heavy items.
I think that CG has a good idea with the larger "Off Road" tires. I will pick some up and will fab/install on my cherry picker prior to any other heavy lifting.
I also would like to fab up a type of A-Frame that will move forward and back fairly easily in the dirt - but as always, funds for the project are limited. I think this would really assist me in picking things up and then I can roll the chassis in and out without the cherry picker legs being in the way. Something with an I-Beam top rail and a nice trolley, and while I am dreaming, a 10,000 sq. foot shop would be nice also.
Again, thanks for the advice. This is my first full frame off project and I think I was just really frustrated with how difficult it was to move heavy objects around on the dirt - just me and my 12 year old son doing the work. I know with a little thought and inginuity and alot of help from the great people on this forum, I will get it done.
