Aw! A 32' MH isn't heavy enough to sink in the sand.

I have heard (do not know if it is an Urban legend) that wood is a conductor of electricity and you should not use it for a jack pad as your rubber wheels will protect the rig but having wood will allow electricity to get to the coach through the jacks (in case of a close by lightening strike or a downed power line in the rain).

Does anyone know if that is true? I purchased the plastic ones, from CW, because of this. I guess if it's an Urban legend, at least I have light weight pads!!!

Thanks for the info. I think I'm going to buy the "ramble jack pads" from camping world. Set of four is about $32. Any experience with these good or bad?

Sheila,

Some common insulator materials are glass, plastic, rubber, air, and wood. So no, wood is not generally a conductor. I would be safe with wood for jack pads.

However, lightening is unpredictable. Example; a friend of mine in Mississippi had a basement workshop. Around on side of the shop was a work bench with electrical outlets. Against one far wall was his amateur radio station hooked up to an antenna 200 feet in the air (Tower). In the middle of the room was another work table. It had absolutely no connection of any type to any part of the room except the for legs. He used this just for dismantling a radio to work on over on the bench against the wall.

He left his home and went shopping with DW. A radio he was going to work on had the cover removed and was sitting on the table in the middle of the room. Lightening struck his tower while he was gone. When he returned, the first thing he saw was the radio on that middle of the room table. It look like someone had taken an arc welder to it. His amateur radio had on resistor fried. There was no other damage to the house.

So when it comes to lightening, anything is a conductor.

I use 2X12's cut and rotated so the grain crosses at 90, glued and screwed together. Drilled holes so I can use the awning rod to position them

Dry wood is not a very good conductor. Neither is the fiberglass poles linemen use. Actually, pure water is a poor conductor. Add a little salt and Zap.

I use 2x10 with a rope attached to pull them out when ready to go..I have had one crack, but wood is inexpensive.. The awning hook is a good idea

Following a design my son-in-law made for a neighbor of his, I'm going to make some for next season.

My jack feet are 8" square, so I'm planning on using a 10" square perimeter frame of 2 x 4's with stiffeners running diagonally from corner to corner, polyrope through two opposite sides, then 3/4 ply top & bottom. All the joints will be 45-degree mitered and the cross-over of the diagonals will be half-cut through each piece.

Should be rugged enough and not too heavy or hogging too much space in the cargo bay.

Like a bunch of people just said 2 x 12 with 3/4 ply wood on each side, we carry 6 of them in case site is way out of level. Drilled a couple holes in them so you can grab them with the awning rod.

I bought a 4x4 pressure treated post and cut it in fourths and put an eye hook on one end so I can grap it with my awning hook.

I use 3/4" Marine plywood 12" X 18". I never extend my jacks without them being in place. Concrete will crack, asphalt will get soft, and dirt/sand will get wet and allow jacks to sink. I don't want any problems for myself or create a problem for someone else.

Our coach, at 50K+ lbs., is too heavy for the Camping World jack pads, and since non-local wood products are banned in many areas, we now use Summit Products Jack Pads, which is the same company who makes the stainless steel trim and step covers:
