No, I had a couple of low ball offers and decided to hang on to it. It turned out to be a good choice because my son bought a 40' park modle trailer for his property up in the French and I can spend as much time as I want up there.
Mine is the 6X6 and I have no trouble taking it out into any depth of water, it is nose heavy but even with my weight and loaded with gear I have tons of freeboard. Moving from side to side, netting fish, it's far more stable than a canoe and I have never taken on water. Besides that, you can't sink them as long as you have air in those tires.
My son did put a 2hp motor on his, switched back to the electric, it was much easier than reaching over the seat to start it. Also there's something special about the silence when you are way back in the bush.
Even with the battery, if it does go dead you are never stuck, just start the Argo , it moves surprisingly well in the water under it's own power. In fact often if I am trolling for pike I just run the Argo, the turbulence from the wheels seems to excite the pike.
