Anything that hauls a load and is cheap! You can built a cheap pontoon (cost ofcourse).
I envy you! I would love to have my own island.
There's one of those places they send managerial staff to to "bond" by doing outdoor activities like making rafts, clay shooting, etc. - maybe I could offer them the valuable opportunity to have as one of their challenges, to build a raft fit to carry a ton of pickup truck across the lake?
