Air compressor for winterizing

For me the 12VDC TANKLESS 150PSI portable Air Compressor works the best. Most of my camping is OFF-ROAD without 120VAC PEDESTALS.

Purchased from AMAZON

I can sit my small tankless compressor on the tail gate of the truck and direct connect the 12VDC CABLES to the BATTERY BANK on the trailer. The AIR HOSE is long enough to walk around my trailer and truck tires from this position.

I use my 12VDc Compreesor for blowing out the water lines in my trailer by connecting to the CITY WATER PORT using an AIR COMPRESSOR air adapter...

Being a TANKLESS model the air compressor is slow bringing up the resulting air pressure and works ideal for me to start the air compressor and walk inside the trailer to open the sink spigots etc...

The 150PSI Air Compressor airs up all of my Truck and Trailer tires just fine...

I store this small footprint air compressor in its neat carry bag under the rear seat of my SUPER CAB truck.

Just slightly off topic but you are using screws to put down the floor of the deck aren't you and just nailing the framing?
Some compressor mfgrs have a list of the amount of air that various tools use which you can use to determine the size of the compressor.

Good advice above...I'll also add - oil-less.

I had one very similar to this, but an older model. It gets up to 120 psi. I've used it for everything, including an air nailer and blowing out the waterlines in the camper. Also, it has blown up a LOT of bicycle tires, wheelbarrow tires, and automobile tires. I also have an attachment that just blows. Works OK for blowing short blasts to remove dust and such. Got it at Lowes.

Here's a decent cheap portable one at Harbor Freight.

But as mentioned, more volume makes it much more versatile.

If you buy a compressor, get a 150 psi unit. The cost isn't much more than a lower psi model.
The smaller units take longer to air up your tires and may not do the job.
You may as well get something that will do more than blow out the lines on the RV.

The larger the tank the more you can do with a compressor. The small portable units have enough cfm for tires, blowing out lines etc. For air tools lke air wrenches you need the larger units. At home Depot and Lowes you will see on the side of the tank what they will handle.

To properly blow out an rv with air, you need a compressor capable rated at 4+ CFM @ 90 psi.
Compact Jobsite compressors are generally inadequate to supply the volume of air at pressure needed to blow a rig dry. They are designed to power a couple of air nailers with a lower supply demand.
For the same money, go get a 30 gallon 1.5 hp from your box store that will handle all your needs and outlast the compact.

Just about all air compressors come with an air pressure regulator, so you can run up the PSI for those air tools you use, and lower the psi for duties like blowing dust around or pumping up tires in a bike. What you really need to be wary of are volume and storage. Personally, the more volume you can practically store, the better. I have a 30 gallon unit and it can run all my air tools from a nail gun to my impacts wrenches and air hammer. To run tools like paint sprayers and impact wrenches, you need lots of volume, at least 25 gallons worth of air for most air tools, and maybe 50 or more gallons for paint sprayers to maintain a constant spray pressure. But for things like a nail gun, you only need a 1 or 2 gallon unit.

However, if you need to drag your air compressor to somewhere like a roof or through doorways and all around, make sure you have a wheeled unit or make sure it's small and light enough to take around with you.

So consider how you will use the air compressor (just nail guns and occasionally pumping up tires? Or any intense use like paint sprayers or impact wrenches). Consider where you will use it (In the house? Garage? Roof? etc...). That will help guide you into selecting the right compressor for you.

Yes you can. And for winterizing, and oil less pancake compressor will be just fine. I recently ordered one from Amazon, a 150 psi Porter Cable and it came with a nice little accessory kit which included a 25' hose. I have also used it with a nailer. $127.00 which was cheaper than the local big box stores.
