Got shocked last night when stepping from the TC while holding onto the ladder in the back. We have had it plugged in previously and didn't have an issue.

We however took it off the truck and it is on the ground now. What do we need to do to ground the camper? Rod in ground with some copper wire?

Also, followed the ground wire in the utility box to the point that it was screwed to the frame. It then loops around to a bracket to the LP lines. Why is that?

The shock you got was probably a static electric shock. You can generate enough static just by walking on a carpet to get a shock, assuming its dry enough. I live in the great white north so every winter its extremely dry anywhere the heat is on (inside the house) so static shocks are just a fact of life. we walk around with car keys in our hands and touch them to door knobs before grabbing the door knob. It still gives a shock but it hurts a lot less.

If you think that the shock you got was from the AC power, I'd have an electrician look at it for safety sake. There could be a freyed wire or loose connection somehwere that's contacting the frame. If this is the case, it can be deadly (no joke).

Your camper should be grounded as soon as you plug in the AC power. The ground wire in the plug/cable should connect back to your house's (or campground's) ground. Other than that it should be grounded through the jacks. If not try putting a wire between the camper frame and one of the jacks. as soon as the jack makes contact with the ground the camper will be grounded. This will take care of static electric build up in the camper, not a short in the AC wiring.

The propane lines are grounded so no spark can be generated around any potential LP leaks. That said, if its dry out you can generate enough static build up to generate a spark into the LP lines (since they're grounded) so ground yourself to part of the camper frame before you start touching the LP lines.

All is well in regards to the electric. Turns out the cord we were using had a broken ground prong so alas, the camper was not grounded. We are probably going to rig up a grounding rod that has a clamp on one end and a rod on the other so we can shove the rod in the ground and then clip the other end to something on the camper just to make sure.

We successfully got the plumbing working and got one tank of bleached water through everything.

Still need to tackle the copper tubing for the LP gas!
