I was leaning towards suggesting a KRA 4107 or similar. 40 inch, pretty basic. Cost about $2000 less 40% discount. After discount its in the ball park of full price for a higher end Craftsman. Get a top box when the space runs out. Could likely be resold for a decent price if its not needed or wanted in the future. There are no bargain tool truck used boxes locally. Trust me I have been checking for months.
