Oh you big meanie Natasha!
Re the hooked to a truck bit, I remember going to hire a trailer once & it was so light & perhaps imbalanced that when my friend & I both stood in the 'escape door' at the front, it tipped up!!
I wouldn't consider a float like that safe even when hooked to a vehicle. When I was in the market for one I passed over anything that wasn't stable & heavy enough to safely load a horse without hooking up. Tho I still chock it with bricks when I use it like this, for Justin.
