cwsqbm: That's where they get you! I'm a pretty good welder, been employed as one at times in the past. Also, trained as a machinist but never searched for work in that field. I could do the work but I still wouldn't be certified for any more than the 5,000 lbs the maker rated it for.
Chris: I keep a close eye on all of my connections, particularly the hitch. I lost a 42' trailer running 65 mph down I20 in Mississippi years ago due to a malfunctioning fifth wheel. The nose of the trailer fell on the tires on the rear axle and locked them up and brought me to a quick stop in the right lane of the interstate. Two things saved my butt. One was it was 11:00 PM and no traffic and the other was the trailer was empty. I don't know if visually and physically inspecting the connection would have made a difference but I do know that a couple times since, I have discovered a fifth wheel not latched good, that may or may not have held, but I take no chances. I put my hands on things to see if they will move and eyeball them up close. A procedure I highly recommend for all.
The final destination is not my goal. My goal is the trip itself.
