Carrying generator on front cargo rack good or bad idea

I was curious if what I do is not such a good idea. I have a cargo rack on the front of my 2011 Chevy D/A. I have generator attached to it and it sits in front of the big opening for the tranny cooler on the lower bumper. I only use this on the front with my 3000 pound truck camper and pulling my 3000 pound boat. When I use my 12k fiver the rack is on back of my 5th wheel. Now I have taken several trips like this and the tranny temp seem to get at the highest around 190 when it is 90+ degrees out. I don't travel a lot like this but maybe 2 or 3 thousand miles a year. The engine temp never budges. There is still room on both sides of the big opening on the lower bumper and the generator sits out in front about 12 inches. The temp seems to be about 20 degrees higher when it s warm out when the generator is mounted on the front. I figured these temps are acceptable and I am not doing any harm. Am I wrong and would you run this way or not?


thanks
