What SUV's will tow Jayco Jay Flight 32TSBH or Eagle 324BTS

I made a spreadsheet that calculates everything, since the calculators I used on other websites did not seem complete, or clear/easy. However, the formulas might need some adjustments because I am not that experienced with RV stuff.

This shows me that the Excursion would NOT work, and the Yukon/Suburban 8.1L 4.10 transmission WOULD INDEED work! (or am I doing it wrong?)
