Just a general reminder to all 5th wheel owners... If the battery in the trailer is dead, you most likely have a good one in the truck you are trying to hook up. Use jumper cables and raise the trailer to the height you need it. Leave it just a little low so the weight lifts off of the legs when you hook up. Then pull the pins and raise the legs for travel.
I have cables long enough to reach the trailer battery when hooked up so I could raise the legs after being hooked up.
Also, in the two times I have had to do something like this to unhook, both time I forgot to unhook the umbilical cord before pulling out from under the trailer. Especially after doing something unusual when hooking or unhooking, start over and walk through your normal steps before proceeding.
Jumpering off these new trucks with all their electronics is not a very wise thing to do, plus the chance of blowing alternator diodes.
Tell you what, compare the motor size on your landing gear to the starter on your truck. As long as I am intelligent enough to hook up the cables correctly, I have no fear of hurting a truck by jumping another 12 volt system.
Unless of course you can show me in the manual where it says you shouldn't do it.
Has nothing to do with the landing gear motor. It is the surge of current hooking the truck to the dead batteries in the trailer or another vehicle.
