Having lost a wheel that I torqued properly with a torque wrench I later found it was my own stupidity that I didn't clean the mating surface on the hub.
There was surface rust on the face of the brake drom and when I changed the wheel to a different style the rust was under the mating surface of the new wheel. It powdered causing a loss of torque on the lug nuts as I was driving. Lost the 35 inch wheel 95lb wheel assembly on a 6,000lb jacked up K5 Jimmy at 60mph. The wheel rolled down through the median through oncoming traffic hit a curb that launched it about 20ft in the air and when it came back down it slammed into the passenger side door of a Ford ranger that was stopped at the cross street. Thankfully nobody was injured but it did $1800 damage to a truck with $2000 fair market value.
Wire brush wheel on the drill would have prevented it.
Cool read
I have a little 4x6 enclosed cargo trailer that I camp out of I am trying to figure out how to stream line behind both my 4runner and my Previa and a lot of ideas that you have posted will help. The roof height is dead even with the 4Runner when hitched so I have that going for me. The Previa is close to the same overall hight.
It is raised so I can pull it off road but I think an adjustable tongue so I can pull it up tight to the trucks on the hwy and some sort of boat tail on the rear door will help. Maybe a Kamm style tail on the trucks to take up some of the gap.
Look forward to the next updates.
