Phil,
I knew I forgot something on the specifications. It will actually support the weight of the Montana, but I erred on not providing enough of a footprint. Geeesh!!!! FYI, the 21 floats will support a total of 18 tons!!!So if each section weighs around 400 pounds for a total of 4 tons then it can hold the 3400RL with ease.....provided the river weight police don't come after me!!!
Bingo
