Removing Windows From a Junked Trailer

I know of a junked Airstream about the same year as mine that I was thinking of getting some windows off of. I think the trailer has been rolled at some point and panels and windows were replaced. I will probably take the two front wing windows and one of the stack windows. I may also get one of the other windows if the large opening stack window is a different size than the two side rear bedroom windows. I know there is a mixture of buck rivets and Olympic rivets that have not had the heads shaved and still have the pin sticking out. I was wondering how long and how much of a pain it will be to remove these windows with the hodge podge mess of rivets. Will I need special tools? Would a rivet removal tool help speed things up. I don't want to waller out the holes in the windows frames. I have one oval window that needs repair/replacing and a large fixed window next to the door that has water in it. I figure I could practice on the donor windows before I ruin my one of a kind windows. My wing windows are good but they might get hit with a rock. I have not talked price with the guy yet. He is not an Airstream salvage yard so I may get them pretty cheap if I remove them. I may also bundle to get a deal on a new old stock fridge. I already bought a new furnace off him for half retail. It seems to be working fine.
