This table system is much better than the stock ETI table that uses two separate poles. The 4 way slide allows you to move the table in any direction. The Springfield base rotates, allowing the freedom to orient the table at any angle.
Here are a couple of threads describing this system:
Both the pedestal and slider are new and have never been used beyond testing. I decided shortly after purchasing them to use an alternate table that isn't attached to the trailer. The Dicor slider became unavailable shortly after I received mine. I think I may have purchased the last one. Thread:
Our family is going to the Escape Trailer Rally (May 26 - May 28). After that we are visiting ETI on May 29th. One option is for us to leave the table base at ETI for whomever buys it.
I paid about $500 for both items, and had the Springfield pedestal professionally modified to attach to the Dicor slider. Given that the Dicor 4 way slide is no longer available, I think it is still worth around that much. My plan is to sell it to the best offer that I get before the rally.
