I have found that you can only get about 10 psi less into a tire than the rated max. pressure of the unit .

What ever compressor you chose, for example, if you want 100 psi in a tire, your unit must be rated at 110 psi or higher. To get the max out of any unit, push the air chuck valve in until the compressor starts to run and then hold the chuck on the valve stem until the compressor shuts off (this only applies if you want the compressors max. available pressure).

If you don't want to kneel there for an extended period of time, which I don't want to do, get one of these "locking" chucks. You just place the chuck straight on the valve stem and then angle it slightly to "lock" it on. When ready to remove it, just angle it slightly to the straight on position. You can't find this in auto parts stores- at least I couldn't. It is used primarily in truck and some auto tire shops.

If you go slightly over the pressure you want-- no problem! Just use you air guage and put it lightly on the valve stem, releasing some air, until you get what you want.

Good luck with your choice ,

I apologize to everyone for not reading all the pages of replies. I followed a link from a closed thread in general discussion. Since I'm retired and not in a rush to air up tires, I am well satisfied with this: Harbor Freight Tools
150psi, high volume,12VDC compressor. I purchased one for #39.99 on sale 2 years ago, things change_.

Air Compressor

I use the compressor Ray refers to, Harbor Freight item # 93186. A word of caution. You must start the compressor before you connect it to tire, or you will blow the fuse. I have added several feet of wire to the compressor to reach all tires and this did not affect its operation. Suggest you use a heavy gauge of wire. Unit gets hot, cool often.

Tire Inflation

I have a 2008 Winnebago Tour. I start my engine and put it into fast idle before using my on-board compressor to inflate my tires. I carry a 50 foot air line and a digital truck tire gauge with braided stainless steel extension. Makes the job quick and easy.

I must be missing something. We already have one of the best air-compressors made, which is connected to a diesel motor. For a few minutes at Lowes and a few bucks, it's plumbed and ready to air almost anything. I'm new to M/H camping, but that's what worked for years with tractor trailers, and I don't see the difference.

Bud Dee,

There are a few of us out here that have the old hydraulic brake systems, at least a step up from the old mechanical brakes on vechicles around the 30's.
ie, No nice engine driven compressors. In fact, we don't even have diesel engines .

Maybe now you have a reason to get one. After all, it comes with a free air compressor.

UMMmmmm - perhaps you didn't notice the specific forum area you posted to - the GENERAL MH discussion area - not ALL of us here own or drive a later model diesel MH - or a later model ANYTHING!

Congratulations on YOUR neat later model diesel rig with nifty built-ins - the REST of us more common peasants will have to continue to cheerfully "eat cake" - ala Marie Antoinette...

My nifty diesel does have a "built in air compressor" that I do use to top off tires, but I am seriously considering buying a Craftsman 150psi 120v compressor ...though the 150psi 12v from Harbor Frieight does sound tempting ...having the 12v option would make it a little more handy, but I am involved in a dispute with Harbor Freight that I appear to be losing after they CHARGED my CC when I returned an item rather than REFUNDING the CC ...so they charged me twice and I don't have the merchandise!! My bank challenged the second charge and reversed it, but I still am out the original price.

Anyway, the reason I am seriously considering buying a free standing compressor is so I don't have to crank up the big diesel and run it 45 min or so to top off my tires. The fronts take 110psi, and that does take awhile to reach. The others go pretty quickly. A free standing compressor would also give me the option of using it AWAY from the MH for airing up tires, in addition to using it for things (air tools, etc) beyond airing up tires ...aha!! ...there's an argument for 120v rather than 12v!!!!

If your a member of the Harbor Frieght Inside Track Club the price for the 12V 150lb compressor is

ITEM 66399-0VGA
ITC Member Price $49.95

Over the long haul thats less than the Fuel to run my Wiz Bang Pusher.

I can always use the 120v compressor by running the generator. If you have a big enough inverter, probably 2000w or larger, you could use it to run a compressor similiar to my Porta Cable 2002. My 1000w pure sine wave inverter cannot handle the load.

In the campground I use mine to help folks out with low tires. I also use it for the golf cart, ATV and the trucks on the property. There always is a 120v outlet on the sites power poles- We are camp hosts in Maine in the summer.

I'm not keen on the 12v compressors.
