have experience with a Shadow Cruiser TC, (1993) ?

I have the 1995 model of this camper. It will fit and should not interfere with the holding tanks/dump valve area. You may need to ensure adequate cab height clearance (2x4 boards would add height and cantilever support if tailgate is not used). Don't think the tailgate would be much cause for concern, though. Just make sure you have good tiedown support. My TC sticker indicates 1868 lb. fully loaded (40lb propane and 17gal fresh water).
