IT is amazing how solid it is !!!!!! If we would have not bought from a member here he was going to crush it because no one was interested in it,I trusted him that he was telling the truth about how solid it was,It spent its life in Georgia and that must be why it is in the shape it's,I mean come on look at the bottom that's factory,I think the best $600 I've spent in a ling time well plus the shipping but I'm blessed to have a solid foundation to do this for my son,The sheet metal has ALOT of issues but remember this is going straight down the track not being restored to factory new conditions,I just hope the mistakes we make (and there will be) don't hurt it too bad--Thanks Guy's Steve
