Frontal area for travel trailers

Thank you all, for your heartfelt advice. I do understand the issue of drag and frontal area. I also know of someone who towed this TT with a similar vehicle without problems. I realize the issue is the risk of overheating the transmission and/or engine. Also, the warranty would be voided. I realize this setup may require going less than the speed limit and crawling up hills. I am willing to do this if I have reassurance there is a good chance I won't ruin my truck. It is automatic transmission. It is interesting to note the frontal area limit on the Nissan Frontier decreased from 60 in 2013 to 30 in 2014. The truck didn't change, I assume the standards changed. The limit is 30 sq ft regardless of 4 or 6 cylinder, 4WD or 2WD.
Anyone have experience towing a TT with a 60+ frontal area with a small truck? Any sad stories? Happy endings?
