I was installing some step stabilizers yesterday on my tracer and I kept getting a small shock from the steps. After a quick look on the interwebs I found the link below and discovered I had what is called "hot skin". I traced it to my extension cord (I had it plugged in at home) which had a short in the ground. Replaced the cord and all is well.
I did not find any info on this site relating to this and it can be a serious issue from what I read.
I wanted to let everyone know check your cords if you plug in at home. Also check your connection at the campsite.
Safe camping FR friends!
Here is a great informational site:
