I have one of those traditional carts with two wheels and a 4x4 post at the front. Never did like tilting it when I moved it and got to look down the barrels of the rifle and shotgun. Added a pair of 6 in wheels to each side of the post and this allowed me to roll it "flat," but rough ground still requred it to be tilted back (6" wheels too small for the really big bumps.)
I considered another pair of 16" wheels from Northern but the cast was pretty close to $50 with shipping and all. And these would still have no "give" in them as they are hard tires.
So today I was at good old Tractor Supply and notice a 4 wheel garden wagon=$100. Checked Home Depot=$75. Fianlly Wal-Mart=$54. The WM one is a bit smaller which is good (smaller is lighter.)
Right now have taken the wheels and post off the gun cart and it sits just about perfectly inside the wagon which has removable sides, too. Since my brother is now cowboying I'm thinking of building another gun cart "top" for the wagon. That way, when I shot by myself I have the little one and when we go together we have one that will hold all our long guns. Something else to spend $$ on. :grin:
