What tongue jack is that you have with the dual wheels? That's looks pretty sweet
Sorry for the delayed reply -
The wheel is from Croft Trailer Supply. It is a TJWK10 Pneumatic Wheel.
The wheel attaches to a Bulldog Swivel Trailer Jack.
The combo is a little expensive, but well worth it. Moving the trailer around is quite easy (although, you have to coax the wheel to turn sometimes). I also have a solid foot, which I use I don't want the trailer to roll around.
