My buddy had the carpet replaced on his travel trailer at the Fleetwood factory in 1999. When he went to pick it up, he noticed the slide was not out all the way, and pushed the button to slide it out the rest of the way. There was a strip of the old carpet still in place. He had to have them repeat the install process (with the slide all the way out) and picked it up the next day (taking another day off work).
So yes it can be done without removing the slide. I don't know how they would remove the slide in 3 hours and put it back.. I think they where pulling someone's leg. . .
I would be looking for another carpet installer.
Fred.
