My cats popped the screen of the petsitters open and got under the trailer, into the sub-flooring. Its going on 3 days now and only one came back. The others are still under there as of this morning. We have 2 traps with Sardines, Tuna, Wet food, and clothing with our scent on it. We crawled under but could not reach without destroying the tarp. My petsitter vetoed that idea, but I am getting desperate. The issue is all 3 were shelter cats caught outside and 2 are still being socialized. What do I do?

Tell the pet sitter you will pay for the tarp... and mean it. Otherwise, all you can do is wait... or perhaps the humane society could get them out with a cat pole.
