I just thought of a problem... I am planning to take my portable air compressor down to Texas with us so I am prepared to winterize the Motorhome when we start coming back North again.Problem is I need to plug it into a lighter socket and do not have such a plug in the back of my rig. I usually plug it into my car that I park behind the motorhome. I will not be bringing a toad.Can I buy a 12 volt cigarette lighter extension cord that might be about 20 foot long so I could run it up to my Motorhome cab plug in?Do they make such an item and where would I be able to buy one?

They used to make one and it was sold at "Radio Shack" or "The Source" in Canada. They are male on one end and female on the other with maybe 20 feet of wire. If you can not find one, you should be able to get the ends or a short one and add longer wire in the middle. Just be carefull to not get too long and check to make sure the wires are not getting hot while in use.

Amazon 12v extentionAmazon.com is where I got mine.

I presume your rig has a trailer light connection at the rear- there are adapters that you can plug right in for 12volt power. Here's a link for the seven-pin style pictured below.

Maybe it's just me, but I doubt that little 12 volt compressor will work very well to winterize. It won't have a high enough volume of air to really blow anything out..But maybe somebody else has a different opinion???B.O.

Hi,

The motor in the compressor won't be too happy about the voltage drop from a longer cable.

You can blow out the lines with a bicycle pump. Even if you don't think that will work, which it will, it will be good enough to get you home.

That's true. The plastic-coated connector end of my extension cable got so hot it warped.

Do you have a generator? If so, a 120 volt shop vac might be a better choice. You'll need one with a blower feature as well as the vacuum. Then a 25 ft extension cord would work without a noticeable voltage drop.
