I am looking to find a relatively portable compressor to blow out my lines for winter. I would like to be able to take it to warm climes on occasion, but would have to blow the lines out on my return to New England if before mid April. Any suggestions?

I was looking into this myself last year...

It's not optimal, but it should work for what you're looking for

Over the years I have had some failures blowing out lines due to condensate in low spots. I now pump pink antfreeze into the lines when coming back to cold climates and have never had a failure. I carry a spare water pump for filling the water tank when boondocking, so I don't have to hold up big water jugs and use the same pump to winterize when needed. I can winterize in about 10 minutes. (water heater is bypassed)
I do carry a truck air 12 volt compressor, but it would be a long process to blow out lines along the roadside with this unit

If you buy a compressor you will want one with at least a 1 gallon tank. You need a delivery of not only pressure but volume to blow the lines. If you use a compressor do not just apply and leave full pressure on the lines. Hit it with a series of short burst because the water will not flow out as fast as air. As you start to reduce the volume of water in the lines longer burst can be applied.

Now that said when we come home while it is still freezing at home we stop at a truck stop and blow the lines and install the antifreeze before we cross into the colder areas. In our case we can then make it home that day. You might end up in a motel one night.
