I bought one of those Valtera traffic cone jack stand supports. It's made for the bare end of the tongue jack. I put a metal skid plate on my jack and just use stacked 4x4s when connecting and disconnecting my TT to my TV. I just don't feel safe enough to use the cone to lift the front of the TT and the rear of the TV. It's a lot of weight. Plus I'm doing it in a truck pull off if heading north as I drag the TT rear pulling out my driveway before installing the WD bars. Going south, I loop through the high school bus lane for installation.
