Transported to camp and home in trailer on top of all our gear.
We were quite a sight on the highway, 2 hour trip - everyone looking at us the entire time.
At camp it took 5 of us to get it on to our trailer and pull it across camp down a steep hill.
We used for a week at camp and it never sank!
Bought it home the same way and it's still intact and really to go again!
Weighed about 300 pounds and took $150 to make.
Step 1: Bottom tubes
then used cardboard cut into triangles to make the tips and wrapped in duct tape.
