If you don't mind going slow-ish and it is not too bumpy, just use a golf bag trolley thing.
With the bag removed u basically have a V shape with wheels at the bottom, strap everything to the top and use mast as a drawbar and you do not have to fabricate anything.
Old school 70's and 80's golf bags on wheels pretty much grow on trees too.
It is dodge, but just thought I'd mention it in case you want free/no building required/need it tomorrow.
