Got a quick question

[AquaMan]

My truck connection (GMC DMax with dual alternators) was enough to power the hydraulic landing gear of my 5er when my battery was dead

I was instructed that it is ' Ground Wire Off First " I could be corrected but that has always been my understanding.

You are correct, as long as its a negative ground system (the vast majority of things), that's the way it is. Now some vehicles can have a positive ground system, which then makes it all opposite but this is going to be the exception, not the rule.

An RV/travel trailer isn't most likely going to have as much metal near the battery as a vehicle, but it's just a best practice to do it this way to be sure. My propane tanks (which rest on the frame) are in very close proximity to my battery, which I usually remove the propane tank cover to gain more access to the battery box behind it.

This has kind of been a hijack, but I'm thinking the OP was satisfied and had his question answered judging by his response in post #6.

Isn't that the case with 99% of the threads on here? I don't think that means we should stop responding. You never know when someone could input some meaningful information on the subject.

You should keep the battery charged.
