I bought a 50' extension to get power down my driveway to the street. Wanting to be able to run my air.Anyhow i got to thinking, leaving it on the driveway will create a situation where it will potentially have to be run over by my wifes car.Another cord i could go around the driveway. Will this all be to much cord?Like i said id like to be able to run the ac when im prepping for a trip.

If you're basically running just the air conditioner, I don't think you'd run into any significant problems. You can have a pretty long run of 10 gauge wire for a 15A or so load without undue voltage drop. The ideal answer would be to measure the voltage and see what sort of a drop you get in practice.If you're running the air conditioner and the fridge and the water heater and a vacuum cleaner...well, that could be more troublesome.I take it that it's not possible to put the RV in the driveway while prepping it and parking the cars on the street? That would seem to me to be the best and easiest solution all around if it's doable.

If it won't fit in the driveway, the cheapest solution is to put the cord, where she'll drive over it, between two 2X4s x 8'. You should have a couple in the garage someplace.Bill

ThirtyWhile Trackrig is a good answer a better one is to get a friend with a table saw to take that 2x4 and cut a dado all the way down for the cord. Then rip the corners off at a 45. I do this all the time for cords and hoses in boat yards. Saves a lot. Matt

A couple of 1X4's would be thick enough and not so hard to drive over IMO.

What is wrong with running it over? That should not hurt the cord at all.
