Tight screws
Who ever owned my rv before must have used epoxy or that red lock tite on the 4 screws that hold the a/c cover on because I used a big phillips head screw driver and cant budge them. I mean I have nev...

You can believe it or don't, I don't actually care. I did work on other people's expensive boats for years before the depression. I did this all the time with screws that were stuck in fiber glass. sometimes some yahoo had used "thread restorer" and other times is was epoxy - even JB-Weld. Heat will make it loose its grip and the screws same screws can be put back in the same holes when you are finished. It only takes about 300°F to get them loose. This is why I specifically said to heat the fastener. I didn't think I would have to say heat only the fastener. That is why a torch won't do the job.
If by the same token, you drill the heads through (on something like a A/C cover) you will not have enough left to grab with vice grips once your pry the cover off. Then you will have unstable parts to try to drill out and you will have to think of some way to replace the threads you destroyed in the process. erial.
Do as you please, as long as I'm not paying for the job, I don't care.

The main problem with your method is that the covers are NOT fiberglass. Fiberglass can withstand quite a bit of heat. These covers are made from heat formed polymer plastic and will soften and deform with heat.
These are sheet metal screws and that although you may not have much left of the heads, once the cover is removed by cutting off the screw heads, the threaded portion of the screw, that sticks through the sheet metal base is easy to grip with pliers to remove the complete screw. No need to drill them out and damage the threads. Once the cover is removed there will probably be 1/2" of the screw thread to grip with pliers that is sticking through the metal base.
