I picked up my 210 with eurobracing near Miami and brought it to Tampa on a trailer. We actually used 3 guys to pick it up and place it on the flat dollies. Wheeled it to the trailer. Set down a smooth then piece of wood on the trailor for it to sit on and another piece under the edge of the tank on the ground where we were going to set it to tilt it into the trailer. Leaned it down to the trailer while picking up and pushing the heavy end onto the trailer. We got on the trailer and centered it towards the front of the trailer. Prior to going down to pick up the tank I had cut pieces of plywood to the size that would wrap around the tank. I screwed thee into each other to make a box on the tank (not a piece on the bottom though). Also be careful not to drill into your tank! Lol...
I then used pieces of 2x4 at the bottom, snuggly bracing the tank. I drilled these pieces into the bottom of the trailer. The tank did not shift and it was protected against any debris that would hit it.
Maybe a little overboard but you have to protect your investment, right?
