I think you'll find buying jacks is cheaper than towing. Back in Sept I had my FWC on a trailer as my pickup is still getting built. On the way home from the from vacation in the Outer Banks I stopped for gas outside of Richmond and the truck would not restart. I was convinced I had gotten bad gas.5:30 on a Saturday evening. I found a towing company that could take the truck and tow the trailer at the same time and got towed home to north of Baltimore. 167 miles. It cost me near $1,200!! Towing Ain't cheap.
Hopefully another FWC owner nearby can help you out with jacks ect.
It's also a good reminder to everyone to always set the parking brake. The parking pawl inside an auto transmission is not really that strong. I just retired from the phone company. If we had ever parked a heavy truck anywhere without using wheel chocks it was grounds for disiplineary action. Not a bad Idea with our campers. (This is just a safety reminder and not a job at the OP)
Sorry for your woes and so glad no one was hurt. Let us know how it works out.
