I went with a 2 adult bike rack on the front of my prior K2500 Suburban. The bikes rode great there but there was 3 issues that finally killed the idea.
1. The bikes do block the radiator area. The transmission temps rise when the bikes where on. 2 bikes was manageable as the 3/4 ton GM's give you a temp gage so you can see what is going on. I only had a 3 deg rise. One of my camping buddies had 4 bikes on his Burb and one hot summer day he was close to boiling over the truck. He ended up taking 2 kid bikes apart and putting them inside to get himself home and then started on Plan B for carrying bikes.
2. The bike tires blocked the headlights. In my case I modified the bike rack so the headlights would shoot over the tires. Being on a 3/4 ton truck I had the ground clearance to lower my wife's bike down about 3" and that helped but it did not totally solve the problem. Ending up getting stuck having to tow after dark one time and the reflection of the headlights on the tires killed the idea.
3. I was alerted by others there are DOT lighting laws that the car directionals lights have to be able to be seen from certain directions and blocking them is not allowed. I found the law back then and I had an issue. I was about ready to mount front directional lights on the bike rack but we changed trucks and the problem went away. I now have the front of the TT rack.
Being a SUV tower has it's issues when it comes to bikes. And a family with kids camping makes it even harder. PS. Don't put them on the back of the camper either. It has issues too.
Hope this helps

I had no problem with airflow, max transmission temp I saw was ~190F climbing the Beartooth mountains. As far as blocking light, zero problem on my Z71 equipped 1500 using this bike rack. I made sure to get one that would keep the bikes as low as possible. The only real downside to the setup was that it made steep driveways much more difficult, I scuffed up some blacktop a few times entering or exiting a restaurant or gas station.
Glad yours worked out for you. Mine was not as good.
My 2003, K2500 Suburban (6.0 with the 4.10 rear axle) towing my camper at the time, (6,600# @ 27ft long) would run 190 to 200F in the summer regularly with no bikes on the front towing the flat lands of Ohio doing 55 to 60mph. This was the tranny pan temp, the Torque converter output would be much higher. The GCW was 13,640# against a GCR of 16,000. When the bikes were added, 203 to 205F was seen in the pan. It was a GM thing as that was a stock setup with their aux tranny cooler.
I finally found the post I made at the time with pics of the setup. The headlights snuck over the top of the tires, but was still a bad reflection at night in the driver's seat. The directional signals had issues. The bikes for sure rode and loaded nice up front just the other issues were a draw back.
You can see this post with pics of the setup on the 2500 Suburban.
Bike Rack - TT rear to front of TV I'm just passing this along to maybe help others think through how to overcome the issues I had. I no longer have the truck and now carry the bikes on the front of the TT.
Hope this helps
