Soldier girl,
This weighs less than lunch.

You preselect, on the built in digital pressure Guage, the pressure you want your tire at, attach the short air hose, turn this on, and walk away. It shuts off when the pressure is reached.
It also inflates Inflatsables© like couches and air mattresses.

The other compressors mentioned here are complicated or require 110v or 12v cord or long obstinate air hoses to be dragged around.

It doesn't get simpler, and the battery also fits flashlights and a 3gallon vacuum and 160 other tools. That little bag is the compressor, battery, charger and a flashlight, the bigger thing next to it is a 3gallon wet/dry vacuum powered by the same battery.

Life can be simple.....

I have and would recommend a 6 gallon pancake air compressor.

New available at Lowes or Home Depot. About $160.
Used on Craigslist about $60 to $80.

But I also have a 35 gallon Craftsman air compressor in my garage
for bigger jobs.

Not too many motorcycles out in the cold weather. When itís warm I flush it whenI get home. We were talking about winterizing

I agree with Phil (post 22). I have a Bostich pancake compressor which easily should fit in the basement storage of most Rvs. I nuse it because I already had it; if I had to buy one now I would buy one of the new Harborfreight super quiet compressors.

Some of the suggested compressors here would take forever to air up an RV tire, let alone six and probably would overheat. I am sure they wouldn't be suited to blow out any water lines because they lack the volume.

I like the porter Cable portable 150 psi compressor.

Anyone have one thatís reliable and that theyíd recommend?
Viair 450P continuous run, is a great compressor for your described needs. I maintain my class A tires to 110psi and blow out my water lines with this model. Works great!!

I use my compressor to winterize. I agree you need one with a tank due to volume of air required.

I have a Harbor Freight 2 Gal Fortress Compressor. It's for 110 only (no 12 volt) but that hasn't been a problem. It tops out at 135 PSI and it will push 2.1 CFM at 90 PSI. I check and fill the tires in my RV every morning before I hit the road and this thing is super quiet (60db) so I can run it without waking the neighbors. The current price is $160 but it goes on sale fairly often or you can use one of their 20% off coupons. Even at that price it's a helluva lot cheaper than a Viair and it's capable of running some air tools around the house when it's not in the RV. It blows out the fresh water system without a problem. It will not blow out my lawn sprinkler system but I didn't expect it could. The best part is that my 4k generator and 30 amp shore power run it without popping a circuit breaker. A lot of the cheapo pan cake compressors will not.

just a note that most of the 20% off Harbor Freight coupon exclude compressors from the discount

It's a bit bulkly and AC only but I have definitely loved having it on board. I carry it in the storage compartment below the driver area on my 24.1 ... also I'm about to plumb some more permanent air hoses to both ends of the rv and maybe even to the inside to blow out dust.

But love being able to just pick it up and go for other uses too with an extension cord if need by (like inflating kayaks etc).

I also have a Viair 00073 in my daily driver (grand cherokee) and full-time onboard air in my wrangler ... all of these will get the job done so there's really no "right or wrong" here.
