Sorry, multitasking today. Day job getting in the way of more important things.
The 300# upgrade is a separate STC that can be utilized after the Rocket STC is completed.
GWI STC (SA00243SE) is $2,995.00 USD
I'm looking at a Rocket but I see it only has GW of 2900. I've found a couple of mentions on MS regarding the STC raising the GW to 3200 but I can't find the details. Can someone offer some info?
