I am picking up my new boat tomorrow and will need to park it on my angled driveway until I bring it to my lake house to live which could be a few weeks. I can't seem to locate any wheel chocks locally/ conveniently located that are up to the chore. All of the ones I'm finding are hollow plastic or not able to handle this much weight. The new Boat and trailer are around 6000 lbs. Does anybody have a suggestion of a creative means to hold the tandem trailer and boat in place while on my angled driveway in time for tomorrow's pick up?
