BACKGROUND: Traded the TT for a new 2016 FR Wildcat. The mattress was super nice with a cushion top BUT.. we missed the 4" Gel topper we had in the TT. The topper came from Sam's club for $99 and even with a new cushion top mattress, when we added the 4" Gel top...ahhhh..sleep was wonderful BUT...the bed was now so heavy that the gas shocks couldn't lift it and it took 2 of us to put in or take things out from the underbed storage.
SOLUTION: FR uses 80# gas pressure shocks and it turns out that replacing those with a higher pressure shock could be done without having to replace the ball-type brackets. We found the best deal on these 120# replacement shocks and now the wife can lift the bed up (and it stays up) with one hand.
We considered 150# shocks but read somewhere that they might be too hard to close so we went with the 120#. Also, I was concerned that the existing brackets might be over taxed so during the installation, I loosened the brackets and applied Gorilla Super Gel (sparingly is enough) and then retightened. Let it dry and with a simple click-release-swap we pulled off the 80# and put the 120#ers in their same place. Its been 3 months and about 35 camping days since the swap out and I'm glad to report this change was a huge success.
