Two stories:
#1) I worked for a company that manufactured bricks, mostly for commercial jobs. Once a year they held a big "Yard Sale" where excess production on commercial jobs are
sold CHEAP to the public - not a huge quantity of any one item, but enough for home planters or such. One day we had someone who bought a whole pallet of brick - about 525 brick if I recall - around 3,500# total. And asked if we could load it on top of her old-school VW Bug.
#2) Confession - one time I **did** tote home some pieces of 20' long fascia trim (1x6 IIRC) on an 8' flat bed trailer. 8' on the bed, almost 4' forward ( to the ball) and 8' aft of the trailer. It was SECURELY tied in front to prevent it from sliding off back on to the road. Proper red flag on the butt end. AND sssslllllooooowwww drive home. Back roads only, watch mirror and pull over anytime ANYONE was behind me.
OK - one more...
Another time someone asked me to deliver a utility trailer to someone else. I didn't know in advance it took a 1 7/8" ball. I only had 2". Trailer was empty. SO... I "wired" it to the top of the 2" ball w/ bailing wire and drove SLOWLY to the destination.
Shrug.
