Wow, that would be too bad IF they went out of biz/stopped making them! :whazzup:
Before those were around, I designed and had a very similar cart built.
In fact, when I first saw the CarryAll Buddy, I was amazed at how similar our designs were!
I told friends about the CA Buddy and they bought them!
If you don't end up finding them I can take close up pics of my cart and give you the dimensions. You can have a raft frame builder or tubing fabricator build it...it's not too complicated or expensive.
You can see what mine looks like here

The handles come off and the wheel (a BMX wheel) comes off and everything folds flat.
