I purchased set of the JT Strong Arms several years ago and dumped the tripod. They work great. Couldn't believe what a difference they made in stability. And, they were literally HALF the price of other brands. I had to add a wooden support to the floor on the center line on my trailer because the floor in the storage compartment n that area was not very thick. Some trailers may not require this bracing. I found the instructions simple, detailed and straight forward.
