What kind of "jacks" are you talking about? Scissors jacks, tripod jack stands, screwpost jacks??? Remember that if you're using a jack that isn't attached to the trailer frame and the trailer or the jack "wobbles" and gets twisted, it could slip out from under the frame and as the trailer settles, the jack could puncture the coroplast. If there is a holding tank or a fresh water tank immediately under the coroplast, you could damage your tank.

That said, if you're talking about scissors jacks, the ones with the big screw rod to pull them up and down, you can attach them to the frame of your trailer, actually even better, to the two bumper standoffs with bolts and self locking nuts. That way they are permanently attached, no need to worry about them slipping or twisting and no requirement to find a place to store them during travel.

Total project time, from gathering tools to cleaning up the mess and opening the adult beverage shouldn't be more than an hour or so.

Good Luck.
