Running Inverter Generator Safely From Pickup

I have a Predator 3500 generator and want to make sure that some/all of these situations are safe for running the generator from the back up my pickup. Thanks for any responses. Basically I want to park my truck a few feet in front of the trailer (back of truck facing front of trailer) and run generator from truck bed with or without rain.

1. Trailer parked right behind back of truck (feet few behind), tailgate down, tonneau cover up, generator on tailgate with exhaust pointing towards side of truck (perpendicular to truck)?

2. Trailer parked right behind back of truck (feet few behind), tailgate down, tonneau cover up, generator on tailgate with exhaust pointing towards cab of truck (no one is inside truck)?

3. Trailer parked right behind back of truck (few feet behind), tailgate down, tonneau cover down (if it's raining), generator in bed of truck (just inside of tailgate) with exhaust facing the cab of the truck (no one is inside truck)? This would be the rain setup.

Say wut?
Generator won't melt if it gets wet.
Why on earth would you direct the exhaust back into the enclosed truck bed making the bed all stinky and hot? Do you think it's going to trap the exhaust and keep it from getting out?
Point generator exhaust away from the truck bed and if you smell exhaust in the camper, it's not working, get a longer extension cord.
