Sorry, the only video of the carrier running since getting everything all together was shot a few months ago at Brent Mullins annual open house and vehicle rally. I'd posted it before but have it again here for reference.

We never seem to have a camera handy for shooting video when out doing test runs. Hopefully we'll get it hauled down to some ranch property in south Texas this fall when the weather cools down a bit and then can shoot video running in and out of the terraced fields and ditches.
As for the mortar platoon arrangment, I'm working on it. I've gotton ATF approval for my 4.2" barrel to be live and functional and only need to make a firing pin stud to complete it now. Shooting 4.2" rounds will make for some really cool video
