Assuming you're not a newly wed and have some disposable income, try using the tool you have drill a hole next to the nail and put a screw and nut in place. Don't mess with the old one, leave it there. Just remember in the RV world, things brake more often than in the S&B world and eventually you will need to make more repairs.
My Thought For The Day
I'm 79 years old and yes I have accumulated stuff over the years, including the practice of buying better tools and making repairs that last. I still have a set of box end wrenches my DW bought for me about two years after we married. We were poor at that time, entry level job and educated at sea, no college. She Bought a Good set of wrenches and I still have them. I no longer rebuild an engine or do heavy work but I still try and repair what I can. I have now started passing these tools on to the maintenance guy at a BSA Camp, my grandson, and granddaughter's husband. Like marriage, good choices last a long time.
