I tend to agree here, I'm all for fixing but a NA diesel with low compression is not the most enjoyable thing to diagnose or repair...
That said HOW much below the allowable spec is it? if its close and you can't afford to fix just add some sort of top tube to the diesel like MMO, 2cycle, Diesel Service or whatever. Your compression will improve a bit. I do know that the Ford NA 7.3 was very reliable for the most part but that was about its only redeeming feature (my father owned a casino bus craftmobile with one). It was not as fuel efficient as other diesel offerings but could run down the road with a cracked block and broken crank if you had to.
Next thing I would offer is if you want the vehicle to be more aero and you could tolerate a loss of area weld and cut the front of the box at an angle (not sure which would be most effective) to the cab, not sure how much it would help if at all. The other possibility would be to extend the rear a bit and add a slope at the proper angle to the rear doors if you could tolerate a lower door height.
Or just lower the hole roof down if you can tolerate less clearance that would do the most with the leave work.
