Here is the frame he was working on. There are a couple of spots that have rusted through, so my husband will be welding in some extra support to make sure it is sturdy for another 50 years! He then coated the entire frame after it was brushed down!
My husband made a trip to Fastenal to pick up truck bolts to sink into the floor for as soon as the flooring starts to go back in. He also plans to add some extra support into places that he will be adding in grey and black water tanks so they can support the weight.
