About to return to truck campers - but need help

If you don't have spring loaded turnbuckles you rip the tie down points off the camper. You either need the Happijack turnbuckles or the Torklift turnbuckles or their equivalent.
I had 4 folding rings installed in the deck of my aluminum flatbed. They held great for 7 years. I used happijack spring loaded turnbuckles front and rear.
