Mark Knackstedt here. Double towing is legal here in Oklahoma. There are length restrictions and of course you need proper equipment (trailer brakes and lights) on the trailers, and a truck capable of pulling the weight. I use a gooseneck hitch on a 1 ton pickup, while you can legally pull doubles with a bumper hitch in Oklahoma it isn't recommended. The advantage is the time and money you save by eliminating the additional trip from home to the campsite.
Getting all hooked up is an art and of course you must plan your trip carefully, while being careful on tight corners. Backing out of a tightspot isn't an option. The RV and boat track behind the truck extremely well. Upon arrival you unhook the boat, park the RV trailer and then hook the boat back up to go to the boat ramp.
I think the author is talking about an either/or when towing. I also have two trailers and when I changed vehicles and bought a new boat, I had to convert the connector so both trailers use the same connectors. However, if he is able to pull both at one time, that is more impressive than finding the short.
I'll have to remember that next time I'm driving thru Mississippi. Faulty signal indicators will be the least of anyone's' concern if cruising the Interstate, one commonly encounters 99' multi-jointed rigs ,,,,, like a train without a track.
I'm with you, JimT... A little searching and I found that "double towing" is illegal in all of the Atlantic states except Maryland, along with Washington, Oregon, and Hawaii. The maxium length of the "captive convoy" ranges from 65-ft in Arizona and California to 99-ft in Mississippi.
99-ft from bumper to bumper. I understand the need for signal lights, but at that length I'm more worried about long-distance transmission costs... =]
I agree Charles, Mark did a great job chasing down that short. I could just see the look on his face when he tried his first fix and the light still came on - frustration aside, it makes you want to solve the problem that much more! I used to fight myself when trying to see outside of my troubleshooting box - how can there be a short when the wiring worked fine before - its just DC voltages in a connector after all. Great job taking it further and finding the issue. I always have to remind myself that vibration and weather related expansion and contraction can cause wires to shift and all kinds of problems on things that used to work fine.
For my sins, I get to bridge the world between mechanical and electrical. When it comes to electrical components, things like dimensions simply aren't the first priority to the designers as well as the technicians.
Altair has released an update of its HyperWorks computer-aided engineering simulation suite that includes new features focusing on four key areas of product design: performance optimization, lightweight design, lead-time reduction, and new technologies.
At IMTS last week, Stratasys introduced two new multi-materials PolyJet 3D printers, plus a new UV-resistant material for its FDM production 3D printers. They can be used in making jigs and fixtures, as well as prototypes and small runs of production parts.
In a line of ultra-futuristic projects, DARPA is developing a brain microchip that will help heal the bodies and minds of soldiers. A final product is far off, but preliminary chips are already being tested.
