Anyway, after a continued search for approximately a 1.5 weeks and sending just one more email I was finally able to secure a purchase from a nice gentleman out in Texas. This guy was extra cool and boxing up the turnbuckles and shipping them was no big issue with him.
|HappiJac S.S. Turnbuckles|
Message in the bottle - "perseverance" seek and you shall find....
HappiJac turnbuckles are specially designed for truck campers whereas ordinary turnbuckles cannot even compare. The front pair (longer barrels) possess an interior shock absorbing spring inside the cylinder . The rear pair designed to hold down the rear portion of one's camper are labeled stressguard tie downs. Not quite sure about the stressguard engineering design concept.
Although I appreciate knowledge of systems that I utilize, I can rest my anxiety I suppose for the the business has been around for over 35 years so they must understand a little about tie down systems.
