My 57' Handyman needs floors from toe boards to tail pan and I wanted to ask the pro's where I should start? I've purchased a "Taiwan" 1 piece floor pan with inner rockers (hope that was the right choice - price was right!) and also USA made toe boards (should be getting them both this week). As for the cargo floor it requires complete replacement as the spare tire well has been consumed and all braces are corroded. Should I begin with cutting out the original "1 piece" floor then bolt my new 1 piece floor onto my new chassis and drop the body onto the floor or should I begin with repairing the cargo floor area first?
