A lot of the chassis mods would depend on the length of the conversion, rear axle placement & GVW.
If you build a 40+ foot conversion with rear axles placed towards the rear, you should consider a double frame. You may also need to increase the ft axle weigh capacity to 15 or 16K lbs as the load ratio would be forward biased.
Rear end ratios for an over-the-road truck are setup for hauling a nominal 80K lbs. Unless you're going to be hauling a 40K pound trailer, chances are you would benifit from a higher ratio, considering fuel mileage, engine wear, etc.
I would agree most of this wouldn't be absolutely necessary however,...as compared to building a house, the "foundation" needs to be correct before starting on anything else.
